Upon mentioning the names of the Sahaabah (Companions), should we say: عليه السلام or رضي الله عنهم ?

Question 10: Is it permissible upon mentioning the name of one of the Sahaabah (Companions of the Prophet) to say, “Peace and blessings be upon him” instead of “May Allaah be pleased with him”?

Answer: It is permissible to say, “Peace be upon him” upon mentioning a Sahaabee (Companion of the Prophet) or some other person, for Imaam Al-Bukhaaree reported in his Saheeh (Book of Authentic Hadeeth), under the chapter on “Sending peace and blessings on other than the Prophet (peace be upon him)” and Allaah’s saying: …and invoke Allaah for them. Verily, your invocations are a source of security for them on the authority of the following chain of narration… read more here.

Invoking Allaah by the honor of the Messenger of Allaah, one of the Companions, or others

Question 13: During Ramadaan, some worshippers follow each two Rak`ahs (units of Prayer) during Taraaweeh (special supererogatory night Prayer in Ramadaan) with a Du’aa (supplication) to Allaah through one of the Sahaabah (Companions of the Prophet). For example, they say, “By the honor of the venerable Sahabee (Companion) so-and-so, we ask Allaah to accept our Salaah (Prayer) and Sawm (Fast).” I have advised them, but it was in vain. I now perform the (Taraaweeh) Salaah by myself in a corner of the Masjid (mosque). Should I perform Salaah with them or do it by myself as I am doing? Please give me a Fatwaa on this and may Allaah reward you with the best reward.

Answer: Making Du’aa to Allaah through the honor or life of the Messenger of Allaah, one of the Sahaabah, or others is not permissible, because acts of `Ibaadah (worship) are Tawqifiee (bound by a religious text and not amenable to personal opinion).
