Sahih al-Bukhari
Oaths and Vows
كتاب الأيمان والنذور
Chapter 31
النَّذْرِ فِيمَا لاَ يَمْلِكُ وَفِي مَعْصِيَةٍ
Musa ibn Ismail narrated to us; Wuhayb narrated to us; Ayyub narrated to us, from Ikrimah, from Ibn Abbas, who said: While the Prophet ﷺ was delivering a sermon, he saw a man standing and asked about him. They said: He is Abu Israil, who vowed to stand and not sit, not seek shade, not speak, and to fast. The Prophet ﷺ said: Tell him to speak, seek shade, sit, and complete his fast. Abd al-Wahhab said: Ayyub narrated to us, from Ikrimah, from the Prophet ﷺ.
Chapter 32
مَنْ نَذَرَ أَنْ يَصُومَ أَيَّامًا فَوَافَقَ النَّحْرَ أَوِ الْفِطْرَ
Muhammad ibn Abi Bakr al-Muqaddami narrated to us; Fudayl ibn Sulayman narrated to us; Musa ibn Uqbah narrated to us; Hakim ibn Abi Hurrah al-Aslami narrated to us that he heard Abdullah ibn Umar (may Allah be pleased with them both) being asked about a man who vowed that no day would pass without his fasting, and then Eid al-Adha or Eid al-Fitr arrived. He said: You have an excellent example in the Messenger of Allah. He did not fast on Eid al-Adha or Eid al-Fitr, nor did he consider fasting on those days.
Abdullah ibn Maslamah narrated to us; Yazid ibn Zuray narrated to us, from Yunus, from Ziyad ibn Jubayr, who said: I was with Ibn Umar when a man asked him: I vowed to fast every Tuesday or Wednesday for as long as I live, and this day has turned out to be the Day of Sacrifice. He said: Allah has commanded that vows be fulfilled, and we have been forbidden to fast on the Day of Sacrifice. The man asked him again, and he gave the same answer without adding anything.
Chapter 33
هَلْ يَدْخُلُ فِي الأَيْمَانِ وَالنُّذُورِ الأَرْضُ وَالْغَنَمُ وَالزُّرُوعُ وَالأَمْتِعَةُ
Ismail narrated to us, saying: Malik narrated to me, from Thawr ibn Zayd al-Dayli, from Abu al-Ghayth, the freedman of Ibn Muti, from Abu Hurayrah, who said: We went out with the Messenger of Allah ﷺ on the day of Khaybar and gained no gold or silver, only property, clothing, and goods. A man from Banu al-Dubayb, named Rifaa ibn Zayd, gave the Messenger of Allah ﷺ a young servant called Midam. The Messenger of Allah ﷺ set out toward Wadi al-Qura. When they were there, while Midam was unloading a saddle for the Messenger of Allah ﷺ, a stray arrow struck and killed him. The people said: Paradise is his! The Messenger of Allah ﷺ said: No, by the One in whose hand is my soul, the cloak he took from the spoils on the day of Khaybar, before the spoils were distributed, will burn as fire upon him. When the people heard that, a man brought the Prophet ﷺ one or two sandal straps. He said: A strap of fire—or two straps of fire.
