Hadith #3

3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) أَنَّهُ سُئِلَ عَنْ رَجُلٍ صَلَّى بِغَيْرِ طَهُورٍ أَوْ نَسِيَ صَلَوَاتٍ لَمْ يُصَلِّهَا أَوْ نَامَ عَنْهَا فَقَالَ يَقْضِيهَا إِذَا ذَكَرَهَا فِي أَيِّ سَاعَةٍ ذَكَرَهَا مِنْ لَيْلٍ أَوْ نَهَارٍ فَإِذَا دَخَلَ وَقْتُ الصَّلاَةِ وَلَمْ يُتِمَّ مَا قَدْ فَاتَهُ فَلْيَقْضِ مَا لَمْ يَتَخَوَّفْ أَنْ يَذْهَبَ وَقْتُ هَذِهِ الصَّلاَةِ الَّتِي قَدْ حَضَرَتْ وَهَذِهِ أَحَقُّ بِوَقْتِهَا فَلْيُصَلِّهَا فَإِذَا قَضَاهَا فَلْيُصَلِّ مَا فَاتَهُ مِمَّا قَدْ مَضَى وَلاَ يَتَطَوَّعْ بِرَكْعَةٍ حَتَّى يَقْضِيَ الْفَرِيضَةَ كُلَّهَا.

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘Umayr from ibn ’Udhaynah from Zurarah who has said the following: “Abu Ja’far, ‘Alayhi al-Salam, was once asked about a man who performs Salah (prayer) without Tahur (cleansing) or forgets it (Salah (prayer)) or goes to sleep. He (the Imam) said, ’He performs its Qada’ (compensatory prayer) in whatever hour he remembers during the night or day. If the time for a Salah (prayer) comes and he has not yet completed what he was to perform as Qada’ (compensatory prayer) he completes what he is to do unless is afraid of running short of the time of Salah (prayer) of present time. Such Salah (prayer) is of greater priority in matters of its time thus, he performs it and when this is complete, he performs that which was missed in the past, and he does not perform any optional Salah (prayer) even one Rak’at, until completion of all obligatory ones.’”
