عَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: مَا صُمْتُ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ تِسْعًا وَعِشْرِينَ أَكْثَرَ مِمَّا صُمْتُ مَعَهُ ثَلَاثِينَ
Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) says: Of the fasts I kept with the Messenger of Allah (peace and blessings be upon him), there were more months of Ramadan with 29 days than those with 30 days.
