"I heard Mu'adhah saying to Aishah: 'Did the Messenger of Allah fast three days of every month?' She replied in the affirmative. So she said: 'Which of them would he fast?' She said: 'Which of them he would fast was not noticeable.'"
قُلْتُ لِعَائِشَةَ أَكَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ ثَلاَثَةَ أَيَّامٍ مِنْ كُلِّ شَهْرٍ قَالَتْ نَعَمْ قُلْتُ مِنْ أَيِّهِ كَانَ يَصُومُ قَالَتْ كَانَ لاَ يُبَالِي مِنْ أَيِّهِ صَامَ
