Q 2: It is related by Imam
that the Prophet (peace be upon him) said,
"Allah will uncover the Shin (disclose the severest Hour), and then all the believing men and women will prostrate themselves to Him. But there will remain those who used to prostrate in this world for affectation and to gain a good reputation. They will try to prostrate (then) but their spine will be one bone."
This Hadith with the same narration was reported by
Al-Bukhari in his "Sahih" book of authentic Hadith and there is no reason to invalidate it or rank it as Da`if (weak). This Hadith is among Ahadith-ul-Sifat (Hadith including Allah's Attributes)
which Muslims should believe in and their minds should accept in a way befitting Allah, without drawing any comparison between Allah and His creatures. Allah says:
There is nothing like Him; and He is the All-Hearer, the All-Seer.
