ذِكْرُ الْبَيَانِ بِأَنَّ دُعَاءَ الْمَرْءِ بِمَا وَصَفْنَا إِنَّمَا هُوَ دُعَاؤُهُ بِاسْمِ اللَّهِ الْأَعْظَمِ لَا يَخِيبُ مَنْ سَأَلَ رَبَّهُ بِهِ
[Machine] He entered the mosque with the Messenger of Allah ﷺ , and there was a man praying, supplicating and saying, "O Allah, I ask You by virtue of the fact that I bear witness that there is no god but You, the One, the Eternal, who begets not nor was He begotten, and there is none comparable unto Him." The Messenger of Allah ﷺ said, "By the One in whose hand is my soul, he has asked Allah by His greatest name, which if He is called upon using it, He answers, and if He is asked by it, He gives." And when a man was reciting in a corner of the mosque, the Messenger of Allah ﷺ said, "He has been given a melodious voice from among the melodious voices of the family of Dawood (David)." The man said, "O Messenger of Allah, shall I inform him?" He said, "Yes, inform him." So I informed Abu Musa, and he said, "He will always be my friend."
أَنَّهُ دَخَلَ مَعَ رَسُولِ اللَّهِ ﷺ الْمَسْجِدَ فَإِذَا رَجُلٌ يُصَلِّي يَدْعُو يَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ بِأَنِّي أُشْهِدُكَ أَنَّكَ لَا إِلَهَ إِلَّا أَنْتَ الْأَحَدُ الصَّمَدُ الَّذِي لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ فَقَالَ رَسُولُ اللَّهِ ﷺ «وَالَّذِي نَفْسِي بِيَدِهِ لَقَدْ سَأَلَ اللَّهَ بِاسْمِهِ الْأَعْظَمِ الَّذِي إِذَا سُئِلَ بِهِ أَعْطَى وَإِذَا دُعِيَ بِهِ أَجَابَ» وَإِذَا رَجُلٌ يَقْرَأ فِي جَانِب المَسْجِدِ فَقَال رَسُوْلُ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّم «لَقَد أُعِطَي مِزْمَاراً مِنْ مَزَامِير آل دَاوُد» وَهُوَ عَبْدُ اللهِ بن قَيسٍ قَالَ فَقُلتُ لَهُ يَا رَسُوْلَ اللهِ أُخْبِرُهُ؟ فَقَالَ «أَخْبِرْهُ» فَأَخْبَرْتُ أَبَا مُوسى فَقَالَ لَنْ تَزَالَ لِي صَدِيقاً
