IBNHIBBAN 206:
from al-Barāʾ —
[Machine] The Prophet ﷺ said, "When a believer testifies that there is no deity except Allah and acknowledges Muhammad as the Messenger of Allah ﷺ in his grave, then this is the saying of Allah, the Exalted, 'Allah keeps firm those who believe, with the firm word, in worldly life and in the Hereafter.'"
ابن حبّان ٢٠٦:
عن البراء —
أَنَّ النَّبِيَّ ﷺ قَالَ «الْمُؤْمِنُ إِذَا شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَعَرَفَ مُحَمَّدًا رَسُولَ اللَّهِ ﷺ فِي قَبْرِهِ فَذَلِكَ قَوْلُ اللَّهِ جَلَّ وَعَلَا {يُثَبِّتُ اللَّهُ الَّذِينَ آمَنُوا بِالْقَوْلِ الثَّابِتِ فِي الْحَيَاةِ الدُّنْيَا وَفِي الْآخِرَةِ} »
