[Machine] I asked Abu Mahdhurah, "How did you give the adhan for the Prophet, ﷺ ? What did you say at the end of your adhan?" He said, "I would say, 'I testify that there is no god but Allah' at the end of my adhan."
سَأَلْتُ أَبَا مَحْذُورَةَ كَيْفَ كُنْتَ تُؤَذِّنُ لِلنَّبِيِّ ﷺ؟ أَيُّ شَيْءٍ كُنْتَ تَجْعَلُ آخِرَ أَذَانِكَ؟ قَالَ كُنْتُ «أُثَنِّي الْأَذَانَ وَأُثَنِّي الْإِقَامَةَ وَأَجْعَلُ آخِرَ أذَانِي لَا إِلَهَ إِلَّا اللهُ»
