‘Ubada b. as-Samit reported God’s Messenger as saying, “Five times of prayer have been prescribed by God. If anyone performs the ablution for them well, observes them at their proper time, and perfectly performs the bowing and showing of submissiveness during them, he has a covenant from God to forgive him; but if anyone does not do so, he has no covenant. If He wills He may forgive him, but if He wills He may punish him.”
Ahmad and Abu Dawud transmitted it, and Malik and Nasa’i transmitted something similar.
Abu Umama reported God’s Messenger as saying, “If you observe your five times of prayer, fast during your month, pay the zakat on your properties, and obey him who has a right to issue commands to you, you will enter your Lord’s paradise.”
I asked the Prophet which action is dearest to God and he replied, “Prayer at its proper time.” I asked what came next, and he replied that it was kindness to parents. I asked what came next and he replied that it was jihad in God's path. He said, “He told me of them, and if I had asked for more he would have told me more.”
