Hadith 7:198
Talha b. ‘Ubaidallah told that when the Prophet saw the new moon he said, “O God, make the new moon rise on us with security, faith, safety and Islam. My Lord and your Lord is God.” Tirmidhi transmitted it, saying this is a hasan gharib tradition.
عَن طلحةَ بنِ عبيدِ اللَّهِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا رَأَى الْهِلَالَ قَالَ: «اللَّهُمَّ أَهِلَّهُ عَلَيْنَا بِالْأَمْنِ وَالْإِيمَانِ وَالسَّلَامَةِ وَالْإِسْلَامِ رَبِّي وَرَبُّكَ اللَّهُ» . رَوَاهُ التِّرْمِذِيُّ. وَقَالَ: هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ
