From him, from Muhammad Bin Al-Husayn, from Safwan Bin Yahya, from Al-A’ala Bin Razeyn, from Muhammad Bin Muslim, (It has been narrated) from one of the two (5 th or 6 th Imam -asws ), said, ‘I asked him -asws about Salāt of the eclipse during a time of the Obligatory ( Salāt ). So he -asws said: ‘Begin with the Obligatory ( Salāt )’. So it was said to him -asws , ‘(Supposing it was) at the time of the night Salāt ?’ So he -asws said: ‘Pray the Salāt of the eclipse before the night Salāt ’.
From him, from Ahmad Bin Muhammad, from Hammad, from Hareyz, from Zurara and Muhammad Bin Muslim, (It has been narrated) from Abu Abdullah -asws having said: ‘When the sun is eclipsed totally and it smoulders, and you did not know, then you came to know after that, so upon you is the fulfilment (of the Salāt missed out); and if all of it did not get eclipsed (totally), so there is no fulfilment (of the Salāt missed out) upon you’.
وَ فِي رِوَايَةٍ أُخْرَى إِذَا عَلِمَ بِالْكُسُوفِ وَ نَسِيَ أَنْ يُصَلِّيَ فَعَلَيْهِ الْقَضَاءُ وَ إِنْ لَمْ يَعْلَمْ بِهِ فَلَا قَضَاءَ عَلَيْهِ هَذَا إِذَا لَمْ يَحْتَرِقْ كُلُّه. And in another report, ‘(he -asws said): ‘When one knows of the (total) eclipse and forgets to pray Salāt , so upon him would be the fulfilment (of the Salāt missed out); and if he did not know of it, so there is no fulfilment (of the Salāt missed out) upon him. This is when the whole of it is not eclipsed’.
