Chapter on the Prayer of the Eclipse
Tahdhīb al-Aḥkām|Volume 3|Book 1|Chapter 9
وَ عَنْهُ عَنْ فَضَالَةَ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ قَالَ أَبُو عَبْدِ اَللَّهِ عَ:« صَلاَةَ اَلْكُسُوفِ إِذَا فَرَغْتَ قَبْلَ أَنْ تَنْجَلِيَ فَأَعِدْ»
And from him, from Fadalah, from Muawiyah ibn Ammar, who said:
Abu Abdillah عليه السلام, peace be upon him, said: “If you complete the eclipse prayer (salat al-kusuf) before the eclipse clears, then repeat it.”
