عن أنس رضي الله عنه قَالَ: قَالَ رسُولُ الله صلى الله عليه وسلم : «ألِظُّوا بـ (يَاذا الجَلاَلِ والإكْرامِ)».
[صحيح] - [ملاحظة: رواية النسائي وأحمد عن ربيعة بن عامر]
Anas (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "Recite frequently: Yādha al-jalāl wa al-ikrām (O Possessor of Majesty and Bounty).”
Sahih/Authentic. - [At-Tirmidhi]
The Arabic imperative 'alizzu' used in this Hadīth means be "persistent in doing something". The meaning: Hold on to this supplication and keep repeating it. This is a virtuous supplication as it includes a name of Allah said to be His most glorious Name, since it encompasses all the attributes of Lordship and Divinity.
