Narrated Anas ibn Malik: A man who had the mark of yellowness on him came to the Messenger of Allah (ﷺ). The apostle of Allah (ﷺ) rarely mentioned anything of a man which he disliked before him. When he went out, he said: Would that you asked him to wash it from him. Abu Dawud said: Salam is not 'Alawi (from the descendants of 'Ali). He used to foretell events by stars. He bore witness before 'Abi b. Arafat to the visibility of moon, but he did not accept his witness.

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عُمَرَ بْنِ مَيْسَرَةَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، حَدَّثَنَا سَلْمٌ الْعَلَوِيُّ، عَنْ أَنَسٍ، أَنَّ رَجُلاً، دَخَلَ عَلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَعَلَيْهِ أَثَرُ صُفْرَةٍ - وَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم قَلَّمَا يُوَاجِهُ رَجُلاً فِي وَجْهِهِ بِشَىْءٍ يَكْرَهُهُ - فَلَمَّا خَرَجَ قَالَ ‏ "‏ لَوْ أَمَرْتُمْ هَذَا أَنْ يَغْسِلَ ذَا عَنْهُ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ سَلْمٌ لَيْسَ هُوَ عَلَوِيًّا كَانَ يُبْصِرُ فِي النُّجُومِ وَشَهِدَ عِنْدَ عَدِيِّ بْنِ أَرْطَاةَ عَلَى رُؤْيَةِ الْهِلاَلِ فَلَمْ يُجِزْ شَهَادَتَهُ ‏.‏
