Among them:

35- “Whoever remains sincerely devoted to Allah, the Mighty and Majestic, for forty days, springs of wisdom will gush forth from his heart onto his tongue.”

⦗73⦘ Imam Ahmad, may Allah have mercy on him, and others narrated this from Makhūl, who reported it from the Prophet, peace and blessings be upon him, with a disconnected chain of transmission.

It was also narrated with a connected chain through Yūsuf ibn ʿAtiyya al-Saffār, from Thābit, from Anas.

Yūsuf, however, is a weak narrator, and his hadith may not be used as evidence.
