and during the first bowing he engages in tasbīḥ (repeating “Subḥāna Allāh”) for a span equal to the recitation of about 100 verses of al-Baqarah, in the second for roughly 80, in the third for around 70, and in the fourth for close to 50. According to the sound position, the prostrations are not lengthened.
I say: The correct view is that they are lengthened; this is attested by the two Ṣaḥīḥs, and al-Buwayṭī explicitly held that each prostration should be about as long as the preceding bowing. Allah knows best.
Performing the prayer in congregation is recommended. One recites aloud in a lunar eclipse but silently in a solar eclipse. The imam then delivers two sermons containing the same essential elements as the Friday sermon, exhorting the people to repent and to do good.
Whoever joins the imam while he is in the first bowing has caught that rakʿah, but if he only joins in the second bowing or the second standing he has not, according to the preponderant opinion.
The solar-eclipse prayer’s time ends when the sun clears or when it sets while still eclipsed. The lunar-eclipse prayer ends when the moon clears or when the sun rises—not merely at dawn, according to the later view—and it does not lapse if the moon sets while still eclipsed.
If an eclipse coincides with the Friday prayer or another obligatory prayer, the obligatory prayer is offered first if there is fear its time will expire; otherwise, the stronger opinion is to begin with the eclipse prayer, after which the imam delivers the Friday sermon, making mention of the eclipse, and then performs the Friday prayer.
If an ʿĪd or an eclipse coincides with a funeral, the funeral prayer takes precedence.
