During the lifetime of God’s Messenger was shooting some of my arrows in Medina when an eclipse of the sun took place. I therefore threw them away and said, “I swear by God that I must see how God’s Messenger acts in a solar eclipse.” When I came to him he was standing in prayer raising his hands. He then began to glorify God, to acknowledge that He is the only God, to declare His greatness, to express His praise and make supplication till the eclipse came to an end. When the eclipse was over he recited two suras and prayed two rak'as.
Muslim transmitted it in his Sahih from 'Abd ar-Rahman b. Samura, and the same occurs in Sharh as-sunna, on his authority, but in the copies of al-Masabih it is given on the authority of Jabir b. Samura.
وَعَن ابْن عَبَّاس قَالَ: صلى الله عَلَيْهِ وَسلم حِين كسفت الشَّمْس ثَمَان رَكْعَات فِي أَربع سَجدَات
وَعَن عَليّ مثل ذَلِك. رَوَاهُ مُسلم
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.
