Arabic
إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى النَّبِيِّ ۚ يَا أَيُّهَا الَّذِينَ آمَنُوا صَلُّوا عَلَيْهِ وَسَلِّمُوا تَسْلِيمًا
English Translation
”Indeed, Allah and His angels send blessings upon the Prophet. O you who have believed, send blessings upon him and greet him with peace”
(Surah 33:56)
Arabic
إِنَّ الَّذِينَ يُؤْذُونَ اللَّهَ وَرَسُولَهُ لَعَنَهُمُ اللَّهُ فِي الدُّنْيَا وَالْآخِرَةِ وَأَعَدَّ لَهُمْ عَذَابًا مُّهِينًا
English Translation
Indeed, those who harm Allah and His Messenger—Allah has cursed them in this world and the Hereafter and prepared for them a humiliating punishment
(Surah 33:57)
