Palace in Jannah (Heavens)
Seal of all Prophets, Mercy for all worlds (Sallallaho Alaihi Wa’Sallam) has said, that whoever recites “Surah Ikhlas” 10 times complete, with grace of Allah (Subhana Wa’Ta’ala) he/she will get a palace in Heavens/Jannah. And if he/she recites 20 times then he/she will get two palaces, 30 times means 3 palaces.
At that point Hazrat Umer (Razi-Allah-Ta’ala anhu) said, Ya Nabi Allah! then we will have multiple palaces.
At this Holy Prophet Mohammed (Sallallaho Alhaihi Wa’Sallam) said, Allah’s kingdom is huge (means He has unlimited power).
