حَدَّثَنَا مُحَمَّدُ بْنُ سَلَامٍ، قَالَ: حَدَّثَنَا يَحْيَى بْنُ أَبِي غَنِيَّةَ، قَالَ: أَخْبَرَنَا عَبْدُ الْمَلِكِ بْنُ أَبِي سُلَيْمَانَ، عَنْ أَبِي الزُّبَيْرِ، عَنْ صَفْوَانَ بْنِ عَبْدِ اللهِ بْنِ صَفْوَانَ، وَكَانَتْ تَحْتَهُ الدَّرْدَاءُ بِنْتُ أَبِي الدَّرْدَاءِ
قَالَ: قَدِمْتُ عَلَيْهِمُ الشَّامَ، فَوَجَدْتُ أُمَّ الدَّرْدَاءِ فِي الْبَيْتِ، وَلَمْ أَجِدْ أَبَا الدَّرْدَاءِ، قَالَتْ: أَتُرِيدُ الْحَجَّ الْعَامَ؟
قُلْتُ: نَعَمْ، قَالَتْ: فَادْعُ اللَّهَ لَنَا بِخَيْرٍ، فَإِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَقُولُ: «إِنَّ دَعْوَةَ الْمَرْءِ الْمُسْلِمِ مُسْتَجَابَةٌ لأَخِيهِ بِظَهْرِ الْغَيْبِ، عِنْدَ رَأْسِهِ مَلَكٌ مُوَكَّلٌ، كُلَّمَا دَعَا لأَخِيهِ بِخَيْرٍ قَالَ: آمِينَ، وَلَكَ بِمِثْلٍ، قَالَ: فَلَقِيتُ أَبَا الدَّرْدَاءِ فِي السُّوقِ فَقَالَ مِثْلَ ذَلِكَ، يَأْثُرُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ»
Safwan ibn Abdullah ibn Safwan, who was married to the daughter of Abud-Darda, said, “I visited them in Syria and found Umm ad-Darda in the house, but not Abud-Darda.
She asked, ‘Are you intending to go on hajj this year?’ ‘Yes,’ I replied. She said, ‘Make supplication to Allah and ask for good for us. The Prophet (sallallahu alayhi wa sallam), may Allah bless him and grant him peace, said, ‘The supplication of a Muslim man for his absent brother is answered. At his head there is a guardian angel.
Whenever he asks Allah to give his brother good, the angel says, ‘Amen, and may you have the same.’’’ I met Abud-Darda’ in the market and he said something similar which was related from the Prophet (sallallahu alayhi wa sallam), may Allah bless him and grant him peace.”
