Ibn ‘Abbas said that when an eclipse of the sun took place, God’s Messenger prayed performing eight bowings and four prostrations. There is a similar tradition from 'Ali. Muslim transmitted it.

وَعَن ابْن عَبَّاس قَالَ: صلى الله عَلَيْهِ وَسلم حِين كسفت الشَّمْس ثَمَان رَكْعَات فِي أَربع سَجدَات وَعَن عَليّ مثل ذَلِك. رَوَاهُ مُسلم
