Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: "The most beloved words to Allah are that a servant says: O Allah! You are pure with Your praise, blessed is Your name, exalted is Your status, and there is no deity worthy of worship except You. And the most disliked words to Allah are that a man says to another: Fear Allah, and he replies: Worry about yourself."

Sayyiduna Anas bin Malik (may Allah be pleased with him) says: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever lies down on his bed and recites this supplication: All praise is due to Allah who has sufficed me and given me shelter, all praise is due to Allah who has fed me and given me drink, and all praise is due to Allah who has shown kindness and mercy to me. O Allah! I ask You by Your honor to save me from the Fire. Then he has uttered all the praises of Allah that have been described by all creatures."

Sayyiduna Abu Hurairah and Sayyiduna Abu Sa‘id (may Allah be pleased with them both) bore witness that the Messenger of Allah (peace and blessings be upon him) said:“When a servant says: There is no true deity except Allah and Allah is the Greatest, Allah Almighty says: My servant has spoken the truth, for I am indeed the only true deity and I am the Greatest. When the servant says: There is no true deity except Allah, He is alone, Allah Almighty says: My servant has spoken the truth, for I am indeed the only true deity, and I am alone. When the servant says: There is no true deity except Allah, He has no partner, Allah Almighty says: My servant has spoken the truth, for I am indeed the only true deity and I have no partner. When the servant says: Allah is the only true deity, sovereignty belongs to Him and all praise is for Him, Allah Almighty says: My servant is truthful, for I am indeed the only true deity, sovereignty is Mine and all praise is for Me. When the servant says: Allah is the only true deity and there is no power to avoid sin nor strength to do good except by His help, Allah Almighty says: My servant has spoken the truth, for I am indeed the only true deity and there is no power to avoid sin nor strength to do good except by My help. Whoever is granted the ability to say these words at the time of death, the Fire will not touch him.”

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "Do you want to strive fully in supplication? (If you do) then say: O Allah! Help us to thank You, to remember You, and to worship You in a good manner."

Sayyiduna Anas (may Allah be pleased with him) narrates that when the Messenger of Allah (peace and blessings be upon him) prayed for someone, he would say: "May Allah grant you the prayers of righteous people, who stand in prayer at night and fast during the day, and who are neither sinners nor evildoers."

It is narrated from Sayyiduna Shaddad bin Aws (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Shall I not tell you the chief of supplications for seeking forgiveness (Sayyid al-Istighfar)? (It is this:) 'O Allah! You are my Lord, You created me, I am Your servant and the son of Your servant, and I am upon Your covenant and promise as much as I am able. I seek refuge in You from the evil of what I have done. I acknowledge Your favor upon me and I confess my sins. Surely, none forgives sins except You.' Whoever recites this supplication in the evening, Paradise will become obligatory for him."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When you reach the morning, say: O Allah! By Your power we have reached the morning and the evening, by Your power we live and by Your power we die, and to You is the gathering. And when you reach the evening, say: O Allah! By Your power we have reached the evening and the morning, by Your power we live and by Your power we die, and to You is the return."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) would recite this supplication in the morning: "O Allah! With Your help we have entered the morning and with Your help we have entered the evening, and with Your help we live and with Your help we die, and to You is the resurrection." And in the evening he would recite this supplication: "O Allah! With Your help we have entered the evening and with Your help we have entered the morning, and by Your power we live and by Your power we die, and to You is the return."

Amr bin Shu'aib narrates from his father, who narrates from his grandfather, Sayyiduna Abdullah bin Amr (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) said: "Whoever recites this phrase one hundred (100) times in the morning and one hundred (100) times in the evening—that is, a total of two hundred (200) times: «لاَ إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ، لَهُ المُلْكُ، وَلَهُ الحَمْدُ، وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ» 'Allah is the only true deity, He is alone, He has no partner, sovereignty belongs to Him, all praise is for Him, and He is capable of everything'—then (in terms of rank and status) neither those before him will surpass him, nor will those after him be able to reach his (rank), except for the person who does more than this."

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said to Sayyidah Fatimah (may Allah be pleased with her): "What is preventing you from listening to my advice? Recite this supplication morning and evening: 'O Ever-Living, O Sustainer of [all] existence! By Your mercy I seek help; set right all my affairs and do not leave me to myself even for the blink of an eye.'"
