Next, he made the takbir and made a long ruku', but it was not as long as the recital. Following that, he raised his head, saying: 'Allah hears him who praises Him. And to You, our Lord, belongs the praise.' Afterward, he stood and made another long recital but it was shorter than the first one. Again, he made the takbir and made a ruku' that was shorter than the first one. Then, again he said: 'Allah hears him who praises Him. And to You, our Lord, belongs the praise.' After this, he prostrated. He did the same in the next rak'ah and finished four ruku' and four sujjud. The sun appeared again before he finished. Finally, he stood and addressed the people and praised Allah as He deserves it and said: 'The sun and the moon are two signs from among Allah's signs and there is no eclipse due to someone's death or life. If you see them occurring, hurry to pray.'" (Bukhari and Muslim)

Next he made another long standing (qiyam) which was also not as long as the first. After that, he made another lengthy ruku' but it was not as long as the first one. Again, he made another long qiyam [and recital] but it was not as long as the first one. After which, he made another lengthy ruku' but it was not as long as the previous one. Following this, he went into sajdah [and so on]. When he had finished, the sun had appeared.

If you see it, make remembrance of Allah.‘” (Bukhari and Muslim)
