´Ibn 'Umar narrated that the Messenger of Allah (s.a.w) said:` "Do not talk too much without remembrance of Allah. Indeed excessive talking without remembrance of Allah hardens the heart. And indeed the furthest of people from Allah is the harsh-hearted."

Hadith Takhrij«تفرد بہ المؤلف ( تحفة الأشراف : 7123) (ضعیف) (سند میں ابراہیم میں قدرے کلام ہے، یہ حدیث رسول صلی الله علیہ وسلم نہیں بلکہ عیسیٰ علیہ السلام کے اقوال میں سے ہے جس کو ابراہیم نے حدیث رسول بنا دیا ہے، دیکھیے الضعیفة: 908، و 920)»
´Anas said that:` The Prophet (ﷺ) entered the Masjid and there was a man who had performed Salat and was supplicating. He was saying in his supplication: “O Allah, none has the right to be worshipped but Allah, You are the One Who gives blessings, Originator of the heavens and the earth, Possessor of glory and generosity (Allāhumma lā ilāha illā ant, al-Mannān, Badī`us-samāwāti wal-arḍ, Dhal-Jalāli wal Ikrām).” So the Prophet (ﷺ) said: “Do you know what he has supplicated Allah with? He has supplicated to Allah by His Greatest Name, the one which if He Is called upon by it, He responds, and when He is asked by it, He gives.”
