حَدَّثَنَا عَبْدُ اللهِ بْنُ يَزِيدَ، قَالَ: حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ زِيَادٍ قَالَ لِي عَبْدُ اللهِ بْنُ يَزِيدَ: سَمِعْتُ عَبْدَ اللهِ بْنَ عَمْرٍو، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ: أَسْرَعُ الدُّعَاءِ إِجَابَةً دُعَاءُ غَائِبٍ لِغَائِبٍ.
Abdullah bin Yazid told us, he said: Abdul Rahman bin Ziyad told us, Abdullah bin Yazid told me: I heard Abdullah bin Amr, on the authority of The Prophet, may God bless him and grant him peace, said: The quickest answered supplication is the supplication of an absent person for an absent person.
