حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو عَامِرٍ الْعَقَدِيُّ، حَدَّثَنَا سُلَيْمَانُ بْنُ سُفْيَانَ الْمَدَنِيُّ، حَدَّثَنِي بِلاَلُ بْنُ يَحْيَى بْنِ طَلْحَةَ بْنِ عُبَيْدِ اللَّهِ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، طَلْحَةَ بْنِ عُبَيْدِ اللَّهِ أَنَّ النَّبِيَّ صلى الله عليه وسلم كَانَ إِذَا رَأَى الْهِلاَلَ قَالَ " اللَّهُمَّ أَهْلِلْهُ عَلَيْنَا بِالْيُمْنِ وَالإِيمَانِ وَالسَّلاَمَةِ وَالإِسْلاَمِ رَبِّي وَرَبُّكَ اللَّهُ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ .
Bilal bin Yahya bin Talhah bin `Ubaidullah narrated : from his father, from his grandfather Talhah bin `Ubaidullah that when the Prophet (ﷺ) would see a crescent moon, he would say: “O Allah, bring it over us with blessing and faith, and security and Islam. My Lord and your Lord is Allah (Allāhumma ahlilhu `alainā bil-yumni wal-Īmān, was-salāmati wal-Islām, rabbī wa rabbuk Allāh).” [Sahih (Albani). Tirmidhi: 3451]
