Benefits for this subject:
Abu Hurairah’s name is `Abdur-Rahman ibn Sakhr Al-Azdi based on the strongest of opinions.
This hadith is mentioned
in Jami’ At-Tirmithi under the chapter: What has been reported about the virtue of the supplication.
The meaning for this hadith is the Supplication is the Most honorable with Allah compared to other acts of worship on the tongue.
(” There is nothing…” ) This refers to other kinds of remembrances and acts of worship. This doesn’t contradict Allah’s statement.” Indeed, the most noble of you in the sight of Allah is the most righteous of you. ( Quran 49:13)
( ” More honorable…” ) Better and more excellent.
(” Than supplication.” ) A person acknowledges Allah’s strength and ability when he supplicates to Him. Supplicating to Allah demonstrates a person is in need of Allah, lacks strength, and is servile.
