Aḥmad ibn Muḥammad ibn Yaḥyá is more truthful than him, do not give him permission (to enter)
It was reported that Dāwūd al-ʾAsbahānī (d. 297 AH) arrived in Baghdād from Naysābūr (Nishapur). Dāwūd had a cordial relationship with Ṣāliḥ (d. 265 AH), the son of Imām Aḥmad ibn Ḥanbal (d. 241 AH). So he spoke to Ṣāliḥ, requesting from him if he could be so kind as to facilitate a meeting with his father.
Ṣāliḥ then entered upon his father and said: A man asked me to meet you.
Imām Aḥmad replied: Who?
Sālih said: Dāwūd.
Imām Aḥmad replied: From where?
Ṣāliḥ said: from ʾAsbahān.
Imām Aḥmad replied: What does he do?
It was said Ṣāliḥ was being evasive in describing who he was, but Imām Aḥmad continued to investigate until he figured it out and said:
Muḥammad ibn Yaḥyá (al-Naysābūrī) wrote to me regarding this individual’s affair, that he claims the Qurʾān is muḥdath (of recent occurrence). Do not let him near me.
Ṣāliḥ replied: ‘O father, rather he denies this (accusation) and condemns it.
Imām Aḥmad replied: Aḥmad ibn Muḥammad ibn Yaḥyá is more truthful than him, do not give him permission (to enter).
