[Machine] The Messenger of Allah ﷺ said, "Whoever finds a small amount of an item, such as a rope, a dirham, or something similar, should announce it for three days. If it is more than that, then he should announce it for six days." 'Umar ibn 'Abdullah ibn Ya'laa claimed to have a unique case, which was doubted by Yahya ibn Ma'een and Jarir ibn 'Abd al-Hamid. Among the reasons for doubt was his consumption of alcohol.  

قَالَ رَسُولُ اللهِ ﷺ مَنِ الْتَقَطَ لُقَطَةً يَسِيرَةً حَبْلًا أَوْ دِرْهَمًا أَوْ شِبْهَ ذَلِكَ فَلْيُعَرِّفْهُ ثَلَاثَةَ أَيَّامٍ فَإِنْ كَانَ فَوْقَ ذَلِكَ فَلْيُعَرِّفْهُ سِتَّةَ أَيَّامٍ تَفَرَّدَ بِهِ عُمَرُ بْنُ عَبْدِ اللهِ بْنِ يَعْلَى وَقَدْ ضَعَّفَهُ يَحْيَى بْنُ مَعِينٍ وَرَمَاهُ جَرِيرُ بْنُ عَبْدِ الْحَمِيدِ وَغَيْرُهُ بِشُرْبِ الْخَمْرِ
