Dhul Hijjah | Ihyaaud Deen

عن أنسٍ رضي الله عنه قال كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيهِ وَ سَلَّمَ إذَا دَخَلَ رَجَبٌ قَالَ اَللّهُمَّ بَارِكْ لَنَا فِيْ رَجَبٍ وَّشَعْبَانَ وَبَلِّغْنَا رَمَضَان (رواه البزار والطبراني فى الأوسط)

Hadhrat Anas (Radhiallahu Anhu) reports that whenever the month of Rajab would arrive, Rasulullah (Sallallahu Alaihi Wasallam) would make the following dua, “O Allah! Bless us in the months of Rajab and Sha’baan and take us forth to the month of Ramadhaan.”
