(5) باب ذِكْرِ النِّدَاءِ بِصَلاَةِ الْكُسُوفِ " الصَّلاَةَ جَامِعَةً "
Abu Mas'ud reported that the Messenger of Allah (ﷺ) said:
Verily the sun and the moon do not eclipse on account of the death of any one of the people, but they are the two signs among the signs of Allah. So when you see it, stand up and observe prayer.
