The Messenger of Allah (ﷺ) said: "Whoever forgets a prayer, let him pray it when he remembers it."

"The Messenger of Allah (ﷺ) was asked about a man who slept and missed the prayer, or forgot it. He said: 'The expiation for that is to pray it when he remembers it.'"

"They told the Prophet (ﷺ) that they had slept and missed the prayer. He said: 'There is no negligence when one sleeps, rather negligence is when one is awake. If any one of you forgets a prayer or sleeps and misses it, let him pray it when he remembers it.'"

"The Messenger of Allah (ﷺ) said: 'There is no negligence when one sleeps, rather negligence is when one does not offer one prayer until the time of the next prayer comes and he realizes that he has missed a prayer.'"

"Let any one of you pray it during its time tomorrow."

The Messenger of Allah (ﷺ) said: If you forget a prayer, pray it when you remember it, for Allah says: "and perform the Salah for My remembrance." [1][1] Ta-Ha 20:14.

"Whoever forgets a prayer, let him pray it when he remembers it, for Allah says: and perform the Salah for My remembrance." [1][1] Ta-Ha 20:14.

"The Messenger of Allah (ﷺ) said: 'Whoever forgets a prayer, let him pray it when he remembers it, for Allah says: "and perform prayer when you remember (li dhikra).'" I said to Az-Zuhri: "Is that how the Messenger of Allah (ﷺ) recited it?" He said: "Yes."

"We were with the Messenger of Allah (ﷺ) on a journey, and we kept going one night, then when it was nearly morning the Messenger of Allah (ﷺ) dismounted and slept, and the people slept too. We did not wake up until the sun had risen. The Messenger of Allah (ﷺ) asked the Mu'adhdhin to call the Adhan, then he prayed the two Rak'ahs before Fajr, then he asked him to say the Iqamah, then he led the people in prayer. Then he told us about everything that will happen until the Hour begins."

"We were with the Messenger of Allah (ﷺ) and we were prevented from praying Zuhr, 'Asr, Maghrib and 'Isha'. I felt very upset about that and I said to myself: 'We are with the Messenger of Allah (ﷺ) and (fighting) for the sake of Allah.' Then the Messenger of Allah (ﷺ) commanded Bilal to say the Iqamah and he led us in praying Zuhr. Then he said the Iqamah and he led us in praying 'Asr. Then he said the Iqamah and he led us in praying Maghrib. Then he said the Iqamah and he led us in praying 'Isha'. Then he went around among us and told us: 'There is no group on Earth who is remembering Allah, the Mighty and Sublime, except you.'"

"We stopped to camp at the end of the night with the Messenger of Allah (ﷺ), and we did not wake up until the sun had risen. The Messenger of Allah (ﷺ) said: 'Let each man take hold of his camel's head (and leave), for the Shaitan was here in this place with us.' We did that, then he called for water and performed Wudu', then he prayed two Rak'ahs, then the Iqamah was said and he prayed Al-Ghadah (Fajr)."

"Who will watch out for dawn for us, so that we do not sleep and miss the dawn prayer?" Bilal said: 'I will.' He turned to face the direction where the sun woke them up, then they got up. He said: 'Perform Wudu'.' Then Bilal called the Adhan and he prayed two Rak'ahs, and they prayed the two (Sunnah) Rak'ahs of Fajr, then they prayed Fajr."

"The Messenger of Allah (ﷺ) set out at nightfall, then stopped to camp at the end of the night, and he did not wake up until the sun had risen or had partly risen. He did not pray until the sun had risen (fully), then he prayed, and that was the 'middle prayer' (Salat Al-Wusta)."
