“When anyone of you is fasting, let him not utter evil or ignorant speech. If anyone speaks to him in an ignorant manner, let him say: ‘I am fasting.’”
قَالَ رَسُولُ اللَّهِ ﷺ إِذَا كَانَ يَوْمُ صَوْمِ أَحَدِكُمْ فَلاَ يَرْفُثْ وَلاَ يَجْهَلْ فَإِنْ جَهِلَ عَلَيْهِ أَحَدٌ فَلْيَقُلْ إِنِّي امْرُؤٌ صَائِمٌ
