The brother's doubt is regarding the Hadith of Abu Dhar رضي الله عنه in which the Prophet صلى الله عليه وسلم said that the sun goes and does Sujood under the Arsh of Allah عز وجل. The brother claims that the problem is this Hadith says the sun glides till it reaches the resting place, does Sujood, then Allah عز وجل gives it permission to rise again. But today science tells us that the sun continuously travels around the galaxy, and we know that the sun rise and sunset is caused due to the earth's rotation only.
