The Glory of Allah subhan wa ta'la

Allah in a gathering is a blessed event. It attracts angels who bring with them the blessings and mercy of Allah.The importance of Zikr is the angels will honor a person who performing Zikr.A person attracts their company often The more time he spends in the remembrance of Allah,  he will attract the company of angels and they will constantly remind him to perform good deeds.The existence of angels is not a fabrication of human imagination.Angels cultivate friendship and affinity with those who remember Allah.
Then Allah Almighty says
"who believe let not your wealth and your children divert you from the remembrance of Allah"… (63:10)

As well
"who believe remember Allah much. And glorify Him morning and evening" (33:42–43)
The Holy Prophetsaw has stressed the importance of Zikr in his Hadith.
Hadhrat Abu Musa Ash’arira relates that the Holy Prophets(S.W.A.L) said,
“The comparison between a person who remembers his Lord and the one who does not do so is like that of the living and the dead.” The Person who remembers Allah is alive and who does not remember Allah is dead. This clearly shows how important remembrance of Allah is.
