عن النعمان بن بشير -رضي الله عنهما- عن النبي -صلى الله عليه وسلم- قال: «إن الدعاء هو العبادة». ومن حديث أنس -رضي الله عنه- بلفظ: «الدعاء مُخُّ العبادة».
[حديث النعمان بن بشير: صحيح. حديث أنس بن مالك: ضعيف.] - [حديث النعمان -رضي الله عنه-: رواه أبو داود والترمذي وابن ماجه وأحمد. حديث أنس -رضي الله عنه-: رواه الترمذي.]

An-Nu‘mān ibn Bashīr (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Verily, supplication is worship." Anas (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Supplication is the brain (essence) of worship.''
Sahih/Authentic. - [Ibn Maajah]

Explanation

"Supplication is worship": This Hadīth indicates that calling upon Allah is the basis of worshiping Him, because when man loses hope except in Allah, manifests his weakness, and calls upon Allah alone without turning to anyone else, then he has thus acknowledged the perfection of Allah and His response to prayers, and that Allah is the All-Hearing, Ever-Close, and is over everything Omnipotent. This is genuine worship and the epitome of monotheism. "Supplication is the brain (essence) of worship": This Hadīth means that supplication is the soul of worship which sustains it, just as the brain sustains the human being.
