Ism-e-Azam
Submitted by Mohammed Gilani on
Anas (Radhiyallahu andhu) said that
he was sitting with Nabi (SallAllahu alayhi wasallam) in the masjid when a man who was performing Salaah said,..
اللَّهُمْ إِنِّي أَسْأَلُكَ بِأَنَّ لَكَ الْحَمْدَ لَا إِلَهَ إِلَّا أَنْتَ الْحَنَّانُ الْمَنَّانُ بَدِيعُ السَّمَاوَاتِ وَالْأَرْضِ يَا ذَا الْجَلَالِ وَالْإِكْرَامِ يَا حَيُّ يَا قَيُّومُ أَسْأَلُكَ
Nabi (SallAllahu alayhi wasallam) then said, "He has supplicated to Allah using His greatest name (i.e the Ism Azam), when supplicated by which Allah Ta'ala answers and when asked by which He gives."
