“The Prophet ﷺ did not visit any sick person until after three days.”  

ابن ماجة:١٤٣٧ – حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا مَسْلَمَةُ بْنُ عُلَىٍّ حَدَّثَنَا ابْنُ جُرَيْجٍ عَنْ حُمَيْدٍ الطَّوِيلِ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

كَانَ النَّبِيُّ ﷺ لاَ يَعُودُ مَرِيضًا إِلاَّ بَعْدَ ثَلاَثٍ
