From Mu’aadh bin al-Juhni, the Companion of the Messenger of Allaah – salallaahu ‘alayhi wa sallam, from the Prophet – salallaahu ‘alayhi wa sallam – who said:
“Whoever reads <<قُلۡ هُوَ ٱللَّهُ أَحَدٌ>> << Say, ‘He is Allaah, [Who is] One>> [Soorah Ikhlaas] until he finishes it ten times, then Allaah builds a Palace for him in Paradise as well as additional benefits.
‘Umar(may Allah be pleased with him) said: ‘Then we will have a lot of Palaces, O Messenger of Allaah!’
The Prophet – salallaahu ‘alayhi wa sallam – said: Allaah has more and what is better.”
