(Qur’an...

(Qur’an, Surah Momin 40:60) It is also narrated from His Eminence (aj) that he said: Dua is the source of worship, just as the cloud is the source of rain.[^5] It is also narrated from His Eminence (aj) that he said: Call the Almighty Allah often, as Allah likes the believer who calls Him; and He has promised the believers that he would accept their prayers. And on Judgment Day the Almighty Allah will consider it among the deeds of the believers that He increases their good deeds.

In another tradition it is narrated from His Eminence that: So supplicate more as it is the key to every mercy and success of every need.

And that which is with Allah cannot be achieved except through Dua and indeed, no door is knocked too much but that it makes the widening near for the person who is knocking.[^6] It is narrated from the Holy Prophet (S) that he said: Every Muslim who calls the Almighty Allah with a supplication in which there is no cutting of relations or committing of sins, the Almighty Allah gives him one of the three: Either He accepts the Dua soon; or He stores it for the Hereafter or He removes an equivalent evil from his account.[^7] It is narrated from His Eminence that he said: Dua is the kernel of worship, and no believer calls the Almighty Allah but that He accepts it.
