Al-Husayn ibn Sa'id from Al-Nadr from Yahya Al-Halabi from Ishaq ibn Ammar from Abu Basir, who said: I said to Abu Abdillah عليه السلام: “I send blessings upon the Prophet, may Allah سبحانه وتعالى bless him and his family, while I am in prostration, is that permissible?” Imam عليه السلام said: "Yes, it is like saying SubhanAllah and Allahu Akbar."
