رَوَى زُرَارَةُ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «أَرْبَعُ صَلَوَاتٍُ يُصَلِّيهَا اَلرَّجُلُ فِي كُلِّ سَاعَةٍ صَلاَةٌ فَاتَتْكَ فَمَتَى مَا ذَكَرْتَهَا أَدَّيْتَهَا وَ صَلاَةُ رَكْعَتَيْ طَوَافِ اَلْفَرِيضَةِ وَ صَلاَةُ اَلْكُسُوفِ وَ اَلصَّلاَةُ عَلَى اَلْمَيِّتِ هَذِهِ يُصَلِّيهِنَّ اَلرَّجُلُ فِي اَلسَّاعَاتِ كُلِّهَا.
Zurarah narrated from Imam Jafar ibn Muhammad Al-Sadiq 
that He said:
"There are four prayers that a person may perform at any hour: a prayer that you missed, so whenever you remember it, you perform it; the two units (rak'ahs) of the obligatory circumambulation (Tawaf) prayer; the prayer for an eclipse (Salat al-Kusuf); and the prayer over a deceased person (Salat al-Janazah). These prayers can be performed by a person at any time."
