ما مدى صحة حديث "عليكم بالتجارة فإن فيها تسعة أعشار الرزق"؟

The aforementioned Hadith was narrated by Saeed ibn Mansour, in mursal form, on the authority of Na'im ibn Abdur-Rahman al-Azdi and Yahya ibn Jabir at-Ta'i. Al-Iraqi declared it weak due to its mursal nature, and Al-Albani graded it as weak.
