Hadith #8

8ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ سَمَاعَةَ بْنِ مِهْرَانَ قَالَ سَأَلْتُهُ عَنْ رَجُلٍ نَسِيَ أَنْ يُصَلِّيَ الصُّبْحَ حَتَّى طَلَعَتِ الشَّمْسُ قَالَ يُصَلِّيهَا حِينَ يَذْكُرُهَا فَإِنَّ رَسُولَ الله (صلّى اللهُ عَلَيْهِ وَآلِه) رَقَدَ عَنْ صَلاَةِ الْفَجْرِ حَتَّى طَلَعَتِ الشَّمْسُ ثُمَّ صَلاَّهَا حِينَ اسْتَيْقَظَ وَلَكِنَّهُ تَنَحَّى عَنْ مَكَانِهِ ذَلِكَ ثُمَّ صَلَّى.

8. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah ibn Mehran who has said the following: “I once asked him (the Imam), ‘Alayhi al-Salam, about a man who forgets to perform the morning Salah (prayer) until it is sunrise. He (the Imam) said, ’He performs it whenever he remembers. The Messenger of Allah remained sleeping during the time for the morning Salah (prayer) until sunrise, then he performed it Qada’ (compensatory prayer) when he woke up but moved away from his place, then performed Salah (prayer).’”
