that the Messenger of Allah (ﷺ) said: "Indeed Allah has made a parable of the straight path: At the sides of the path there are walls with open doors, each door having a curtain. There is a caller at the head of the path calling, and a caller above it calling. And Allah invites to the abode of peace and guides whomever He wills to the straight path. The doors which are on the sides of the path are the Hudud (legal limitations) of Allah; no one breaches the Hudud of Allah except that curtain is lifted, and the one calling from above it is his Lord."

that Jabir bin 'Abdullah Al-Ansari said: "One day the Messenger of Allah (ﷺ) came out to us and said: "While I was sleeping I had a vision as if Jibra'il was at my feet. One of them said to his companion: 'Make a parable for him' so he said: 'Listen so that your ears may hear. Hearken so that your heart may understand! The parable of you and your Ummah is but the parable of a king who conquers a land, then he constructs a house in it. Then he places a table-spread in it, then he sends a messenger to call the people to eat from it. Among them are those who answer the call of the messenger, and among them are those who forsake it. So Allah is the king and the land is Islam, and the house is Paradise, and you O Muhammad! You are the Messenger, so whoever responds to you he enters Islam, and whoever enters Islam he enters Paradise, and whoever enters Paradise, he shall eat of what is in it.'"

from Ibn Mas'ud who said: "The Messenger of Allah (ﷺ) performed 'Isha, then he turned and took the hand of 'Abdullah bin Mas'ud until he went with him to the wide valley of Makkah. He sat him down, then he drew a line around him. Then he said: 'Do not go beyond your line, for indeed there shall come some men to you, but do not speak to them for they shall not speak to you.'" He said: "Then the Messenger of Allah (ﷺ) went to where he wanted to go, and while I was sitting within the line, some men came to me that appeared as if they were from Az-Zut (A dark people, either from North Africa or India. See Tuhfat Al-Ahwadhi and An-Nihayah), both their hair and their bodies. I did not see nakedness nor covering. They ended up before me but they did not pass the line. Then they returned toward the Messenger of Allah (ﷺ) and when it was near the end of the night, the Messenger of Allah (ﷺ) came to me while I was sitting, and he said: "I have been awake watching all night' then he entered into the line with me and lay down on my thigh to sleep. And the Messenger of Allah (ﷺ) would snore when he slept. So while I was sitting there, and the Messenger of Allah (ﷺ) was sleeping (with his head resting) on my thigh, there appeared some men wearing white garments, and Allah knows best just how handsome they were. They came towards me, and a group of them sat at the head of the Messenger of Allah (ﷺ), and a group at his feet. Then they said to each other: 'We have not ever seen a slave (of Allah) who was given the likes of what this Prophet has been given. Indeed his eyes sleep but his heart remains awake. His parable is that of a chief who built a castle, then he placed a table-spread in it, and invited the people to eat from his food and drink. So whoever answers his invitation, he eats from his food and drinks from his drink. Whoever does not answer, he is punished - or he said - he is chastised.' Then they alighted and the Messenger of Allah (ﷺ) awoke at that time, and said: 'I heard what they were saying. Do you know who they were?' I said: 'Allah and His Messenger know better.' He said: 'They were the angels. Do you know the meaning of the parable they stated?' I said: 'Allah and His Messenger know better.' He said: 'The meaning is that Ar-Rahman [Most Blessed and Most High] built Paradise, and He invited His Slaves to it. Whoever replies he shall enter Paradise, and whoever does not reply, he shall be punished or chastised.'"

that the Messenger of Allah (ﷺ) said: "The parable of myself and the Prophets [before myself] is that of a man who constructed a house. He completed it and made it well, except for the space of one brick. So the people enter it and marvel at it saying: 'If not for the space of this brick.'"

that the Messenger of Allah (ﷺ) said: "Indeed Allah commanded Yahya bin Zakariyya with five commandments to abide by, and to command the Children of Isra'il to abide by them. But he was slow in doing so. So 'Eisa said: 'Indeed Allah commanded you with five commandments to abide by and to command the Children of Isra'il to abide by. Either you command them, or I shall command them.' So Yahya said: 'I fear that if you precede me in this, then the earth may swallow me, or I shall be punished.' So he gathered the people in Jerusalem, and they filled [the Masjid] and sat upon its balconies. So he said: 'Indeed Allah has commanded me with five commandments to abide by, and to command you to abide by. The first of them is that you worship Allah and not associate anything with him. The parable of the one who associates others with Allah is that of a man who buys a servant with his own gold or silver, then he says to him: "This is my home and this is my business so take care of it and give me the profits." So he takes care of it and gives the profits to someone other than his master. Which of you would live to have a servant like that? And Allah commands you to perform Salat, and when you perform Salat then do not turn away, for Allah is facing the face of His worshipers as long as he does not turn away. And He commands you with fasting. For indeed the parable of fasting, is that of a man in a group with a sachet containing musk. All of them enjoy its fragrance. Indeed the breath of the fasting person is more pleasant to Allah than the scent of musk. And He commands you to give charity. The parable of that, is a man captured by his enemies, tying his hands to his neck, and they come to him to beat his neck. Then he said: "I can ransom myself from you with a little or a lot" so he ransoms himself from them. And He commands you to remember Allah. For indeed the parable of that, is a man whose enemy quickly tracks him until he reaches an impermeable fortress in which he protects himself from them. This is how the worshiper is; he does not protect himself from Ash-Shaitan except by the remembrance of Allah.'" The Prophet (ﷺ) said: "And I command you with five that Allah commanded me: Listening and obeying, Jihad, Hijrah, and the Jama'ah. For indeed whoever parts from the Jama'ah the measure of a hand-span, then he has cast off the yoke of Islam from his neck, unless he returns. And whoever calls with the call of Jahiliyyah then he is from the coals of Hell." A man said: "O Messenger of Allah! Even if he performs Salat and fasts?" So he (ﷺ) said: "Even if he performs Salat and fasts. So call with the call that Allah named you with: Muslims, believers, worshipers of Allah."

So the Jews worked for half a day for a Qirat each. Then he said: 'Who will work for me from the middle of the day until Salat Al-'Asr for a Qirat each?' So the Christians worked for a Qirat each. Then it is you who are doing the work from Salat Al-'Asr until the setting of the sun for two Qirats each. So the Jews and the Christians got angry and said: 'We did more work but were given less?' So He (Allah) says: 'Have I wronged you in any of your rights?' They said: 'No.' He says: 'Then it is my blessing that I give to whomever I wish.'"
