(6) باب مَنْ فَاتَتْهُ مَتَى يَقْضِيهَا
Narrated Qays ibn Amr:
The Messenger of Allah (ﷺ) saw a person praying after the congregational prayer at dawn was over. The Messenger of Allah (ﷺ) said: There are two rak'ahs of the dawn prayer (i.e. the prescribed rak'ahs). The man replied: I did not pray the two rak'ahs before the dawn prayer. Hence I offered them now. The Messenger of Allah (ﷺ) kept silent.
