Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) used to teach us Istikhara just as he used to teach us the Qur'an. He would say: "Whenever any one of you intends to do something, he should first perform two units of voluntary prayer, then he should supplicate with this dua: 'O Allah! I seek goodness from You through Your knowledge, and I seek ability from You through Your power, and I ask You from Your great bounty. You have power, I have no power; You know, I do not know; You are the Knower of the unseen. O Allah! If You know that this matter—here he should mention the matter by name—is better for my religion, my life, and my hereafter, then decree it for me, make it easy for me, and bless it for me. And if You know that this matter is bad for my religion, my life, and my hereafter, then turn it away from me and decree goodness for me wherever it may be, and make me pleased with it.'"

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: When the Prophet Muhammad (peace and blessings be upon him) would see the new moon, he would supplicate: "O Allah! Let this moon rise upon us with security, faith, safety, and Islam, and with that which You love and are pleased with. (O moon!) Our Lord and your Lord is Allah, the Exalted."

Sayyidah Aisha Siddiqa narrates: The Prophet Muhammad (peace be upon him) said: "When someone asks (from Allah), let him ask abundantly, for he is asking from his Lord."

Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said:“Supplication is worship itself.”Then he recited this verse:“Call upon Me; I will respond to you. Indeed, those who are too proud for My worship will soon enter Hell in humiliation.”

Abdullah bin Buraidah narrates from his father that the Prophet Muhammad (peace be upon him) heard a man supplicating: O Allah! "I ask You, indeed I bear witness that there is no deity except You, You are One, the Eternal Refuge, You did not beget nor were You begotten, and there is none comparable to You." So the Prophet Muhammad (peace be upon him) said: This person has supplicated to Allah by His Name, when asked by it, Allah gives, and when supplicated by it, Allah accepts the supplication.

Abdullah bin Buraidah narrates from his father: He entered the mosque with the Prophet Muhammad (peace be upon him), where a man was performing prayer and supplicating. He was saying: "O Allah! I ask You and I bear witness to You that there is no deity except You, You are One and As-Samad, You have not begotten nor were You begotten, and there is none comparable to You." So the Prophet Muhammad (peace be upon him) said: "By the One in Whose hand is my soul, he has asked Allah by His Name, which, when asked by it, He gives, and when supplicated by it, He answers." Then a man was reciting in a corner of the mosque, and the Prophet Muhammad (peace be upon him) said: "This person has been given the melodious voice of Dawud (David), peace be upon him. This is Abdullah bin Qais (i.e., Abu Musa Ash'ari)." The narrator says: I asked the Prophet Muhammad (peace be upon him): "O Messenger of Allah! Should I inform him?" The Prophet Muhammad (peace be upon him) said: "You may inform him." I told Abu Musa Ash'ari (may Allah be pleased with him) this, and he said: "You will always remain my friend." The narrator named Zaid bin Hubab says: I narrated this tradition to Zuhair bin Mu'awiyah, and he said: I heard Abu Ishaq Sabi'i narrate this hadith from Malik bin Mighwal.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: I was sitting in a gathering with the Prophet Muhammad (peace and blessings be upon him). A man was performing prayer. When he went into bowing (ruku‘), he prostrated and recited the tashahhud, then while supplicating he said:“O Allah! I ask You, indeed all praise is due to You, there is no deity except You, You are the Most Compassionate and the Bestower of favors, the Creator of the heavens and the earth, Possessor of Majesty and Honor, the Ever-Living, the Sustainer of all. O Allah! I ask You.”The Prophet Muhammad (peace and blessings be upon him) then said: Do you know what this person has supplicated with? The people said: Allah and His Messenger know best. The Prophet Muhammad (peace and blessings be upon him) said: By the One in Whose Hand is my soul, he has supplicated to Allah by His Greatest Name; when He is called upon by it, He answers, and when asked by it, He gives. (Imam Ibn Hibban, may Allah have mercy on him, says:) The narrator named Hafs is Hafs bin Abdullah bin Abu Talhah, who is the brother of Ishaq, and is the son of the maternal half-brother of Sayyiduna Anas (may Allah be pleased with him).

Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Every person should ask all his needs from his Lord, even if the strap of his sandal breaks, he should ask Allah Almighty for that as well."

Sayyiduna Anas (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "Each one of you should ask your Lord for your needs, even if the strap of your sandal breaks, he should ask Allah Almighty for it."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates this statement of the Prophet (peace and blessings be upon him): "When a person supplicates, he should be abundant in his asking, for nothing is great (i.e., difficult) for Allah Almighty."
