Surah An-Nisa — Ayah 136 (4:136)
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ ءَامِنُواْ بِٱللَّهِ وَرَسُولِهِۦ وَٱلۡكِتَٰبِ ٱلَّذِي نَزَّلَ عَلَىٰ رَسُولِهِۦ وَٱلۡكِتَٰبِ ٱلَّذِيٓ أَنزَلَ مِن قَبۡلُۚ وَمَن يَكۡفُرۡ بِٱللَّهِ وَمَلَٰٓئِكَتِهِۦ وَكُتُبِهِۦ وَرُسُلِهِۦ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ فَقَدۡ ضَلَّ ضَلَٰلَۢا بَعِيدًا ١٣٦
English translation (Saheeh International)
O you who have believed, believe1 in Allāh and His Messenger and the Book that He sent down upon His Messenger and the Scripture which He sent down before. And whoever disbelieves in Allāh, His angels, His books, His messengers, and the Last Day has certainly gone far astray.
- - i.e., renew, confirm and adhere to your belief.
Brief commentary
O believers, be firm in your faith in Allah, His Messenger, the Qur’ān which He revealed to His Messenger and the books He revealed to the messengers before him. Anyone who disbelieves in Allah, His angels, His books, His messengers and the Day of Judgement has strayed far from the straight path.
