"I do not know that the Messenger of Allah ﷺ recited the whole Qur'an in one night, or spent a whole night in worship until dawn, or that he ever fasted an entire month apart from Ramadan."
لاَ أَعْلَمُ رَسُولَ اللَّهِ ﷺ قَرَأَ الْقُرْآنَ كُلَّهُ فِي لَيْلَةٍ وَلاَ قَامَ لَيْلَةً حَتَّى الصَّبَاحِ وَلاَ صَامَ شَهْرًا كَامِلاً قَطُّ غَيْرَ رَمَضَانَ
