it is a reliable supporting evidence for this, and Allāh knows best.

"The dinar is a treasure, the dirham is a treasure, and the qīrāṭ is a treasure." They said, "O Messenger of Allāh, we know the dinar and the dirham, but what is the qīrāṭ?" He said, "Half a dirham, half a dirham, half a dirham." It was recorded by al-Ṭaḥāwī in "Mushkil al-Āthār" (2/107) through the route of Abū ʿAbd al-Raḥmān al-Muqriʾ: Ibn Lahīʿah narrated to us from Ibn Hubayrah from Abū Tamīm al-Jayshānī from Abū Hurayrah who said: The Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam) said it, and he mentioned it. I say: This isnād is good, and its men are trustworthy. Ibn Lahīʿah's ḥadīth is only to be avoided if it is from the narration of those other than the ʿAbādilah from him, for their ḥadīth from him is authentic, as the scholars have stated in his biography. This is from the narration of one of them, Abū ʿAbd al-Raḥmān, who is ʿAbd Allāh ibn Yazīd al-Muqriʾ, and he was followed by the second of them, ʿAbd Allāh ibn Wahb. Ibn Abī Ḥātim mentioned it from his route in "al-ʿIlal" (1/219-220) and said: "My father said: This is a rejected ḥadīth!" There is no basis for this in my view, and it seems he followed the common path regarding Ibn Lahīʿah's ḥadīth. The correct approach is the distinction I mentioned, which is to differentiate between the general ḥadīth from him and the ḥadīth of the ʿAbādilah. And Allāh knows best. From this distinction, you can understand the reasoning behind al-Munāwī's explanation of al-Suyūṭī's statement in "al-Jāmiʿ al-Ṣaghīr": "Narrated by Ibn Mardawayh from Abū Hurayrah," he said: "With a weak isnād, and he narrated it from him in 'al-Firdaws' and left the isnād blank." Its reasoning is that it is possible that Ibn Mardawayh had it from a route other than the ʿAbādilah from Ibn Lahīʿah or from another weak source. And Allāh knows best.
