Jami` at-Tirmidhi Book 48, Hadith 233
“Every Prophet has a (special) supplication which is answered. Verily, I have reserved mine as intercession for my nation, and it shall reach, if Allah wills, those of them who die, not associating anything with Allah.”
“The Messenger of Allah (ﷺ) said to me: ‘Be frequent in saying: “There is no might or power except by Allah, (Lā ḥawla wa lā quwwata illā billāh).” For verily, it is a treasure from the treasures of Paradise.’”
“Allah, the Most High said: ‘I am as My slave thinks of Me, and I am with him when he remembers Me. If he remembers Me to himself, I remember him to Myself, and if he remembers Me in a gathering, I remember him in a gathering better than that. And if he seeks to draw nearer to Me by a hand span, I draw nearer to him by a forearm’s length, and if he comes to Me by a forearm’s length, I draw nearer to him by an arm’s length. And if he comes to Me walking, I come to him quickly.’”
