Abu Sa’id and Abu Hurairah (RAA) narrated that the messenger of Allah (ﷺ) said:

“Remind those who are on their death bed of the Shahadah “La'Ilaha illall-ah.” (for them to say it, hoping it will be their last words)”

وَعَنْ أَبِي سَعِيدٍ وَأَبِي هُرَيْرَةَ رَضِيَ اَللَّهُ عَنْهُمَا قَالَا: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ لَقِّنُوا مَوْتَاكُمْ [1]‏ لَا إِلَهَ إِلَّا اَللَّهُ } رَوَاهُ مُسْلِمٌ, وَالْأَرْبَعَةُ [2]‏ .‏
