حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي أَبِي ثَنَا عَفَّانُ ثَنَا هَمَّامٌ أَنَا بِشْرُ بْنُ حَرْبٍ عَنْ سَمُرَةَ بْنِ جُنْدُبٍ قَالَ: أَحْسِبُهُ مَرْفُوعًا: ((مَنْ نَسِيَ صَلَاةً فَلْيُصَلِّهَا حِينَ يَذْكُرُهَا وَمِنَ الْغَدِ لِلْوَقْتِ))
It is narrated from Sayyiduna Samurah bin Jundub (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever forgets a prayer should offer it when he remembers it, and on the next day, he should pray at its appointed time.
