Hawzah News Agency – The merciful prophet of Islam, peace be upon him and his household says:

إنَّ اللَّهَ جلّ ثَناؤهُ يقولُ: وعِزَّتي وجَلالي، ما خَلَقتُ مِن خَلْقي خَلْقاً أحَبَّ إلَيَّ مِن عَبديَ المؤمنِ.

'Verily Allah, exalted be His praise, says: 'By My Might and Exaltedness, I have not created any creature more beloved to Me than My believing servant.'
