What doubtful (unclear) things should be avoided?
حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ مَنْصُورٍ، عَنْ طَلْحَةَ، عَنْ أَنَسٍ ـ رضى الله عنه ـ قَالَ مَرَّ النَّبِيُّ صلى الله عليه وسلم بِتَمْرَةٍ مَسْقُوطَةٍ فَقَالَ " لَوْلاَ أَنْ تَكُونَ صَدَقَةً لأَكَلْتُهَا ". وَقَالَ هَمَّامٌ عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " أَجِدُ تَمْرَةً سَاقِطَةً عَلَى فِرَاشِي ".
Narrated Anas: The Prophet (ﷺ) passed by a fallen date and said, "Were it not for my doubt that this might have been given in charity, I would have eaten it." And narrated Abu Huraira the Prophet (ﷺ) said, "I found a datefruit fallen on my bed."
