A man came to the Messenger of Allah ﷺ and he had the mark of yellowness (of saffron). The Prophet (peace be upon him rarely mentioned a thing which he disliked before a man. When he went away, he said: Would that you tell this man that he should wash this off him.
أَنَّ رَجُلاً دَخَلَ عَلَى رَسُولِ اللَّهِ ﷺ وَعَلَيْهِ أَثَرُ صُفْرَةٍ وَكَانَ النَّبِيُّ ﷺ قَلَّمَا يُوَاجِهُ رَجُلاً فِي وَجْهِهِ بِشَىْءٍ يَكْرَهُهُ فَلَمَّا خَرَجَ قَالَ لَوْ أَمَرْتُمْ هَذَا أَنْ يَغْسِلَ هَذَا عَنْهُ
