الآية رقم (53) - رَبَّنَا آمَنَّا بِمَا أَنزَلَتْ وَاتَّبَعْنَا الرَّسُولَ فَاكْتُبْنَا مَعَ الشَّاهِدِينَ

(53) - (Our Lord, we have believed in what You revealed and have followed the messenger Jesus, so register us among the witnesses [to truth].")

It’s not only about saying that you believe in Allah (swt) but also about believing in what Allah (swt) has sent down. He is a disbeliever who claims to believe in Allah (swt) while he denies the prayers, fasting, Zakat, and Hajj.

( فَاكْتُبْنَا مَعَ الشَّاهِدِينَ ) (…so register us among the witnesses [to truth].”): The Almighty will, on the doomsday, make the believers testify on all the people who denied and disbelieved in Allah’s signs. Besides, the prophet (saws) will be witness on them.
