Ali bin Abu Talib reported,

The sun was eclipsed, so Ali led the people in prayer. He recited Surah Yasin or something of similar length, then bowed for roughly the length of that surah. Then he raised his head and said, "Allah hears the one who praises Him." Then he stood for the length of the surah, supplicating and pronouncing takbir. Then he bowed again for the length of his recitation, and said, "Allah hears the one who praises Him." Then he stood once more for the length of the surah, and bowed again for the same length, until he had made four bowings. Then he said, "Allah hears the one who praises Him," and prostrated.Then he rose for the second rakat and did exactly as he had done in the first. Afterward he sat supplicating and pleading until the sun emerged from the eclipse. Then he told them that the Messenger of Allah ﷺ had done the same.

حدثنا يحيى بن آدم حدثنا زهير حدثنا الحسن بن الحر حدثنا الحكم بن عتيبة عن رجل يدعى حنشا

عن علي رضي الله عنه قال

كسفت الشمس فصلى علي رضي الله عنه للناس فقرأ يس أو نحوها ثم ركع نحوا من قدر السورة ثم رفع رأسه فقال سمع الله لمن حمده ثم قام قدر السورة يدعو ويكبر ثم ركع قدر قراءته أيضا ثم قال سمع الله لمن حمده ثم قام أيضا قدر السورة ثم ركع قدر ذلك أيضا حتى صلى أربع ركعات ثم قال سمع الله لمن حمده ثم سجد ثم قام في الركعة الثانية ففعل كفعله في الركعة الأولى ثم جلس يدعو ويرغب حتى انكشفت الشمس ثم حدثهم أن رسول الله ﷺ كذلك فعل
