Rest your mind; calm your heart
Our Lord! (they say), “Let not our hearts deviate now after You have guided us, but grant us mercy from Your own Presence; for You are the Grantor of bounties without measure.
Qur’an (3:8)
Indeed, Allah knows the unseen [aspects] of the heavens and the earth. And Allah is Seeing of what you do.
Qur’an (49:18)
Say, “We have believed in Allah and in what was revealed to us and what was revealed to Abraham, Ishmael, Isaac, Jacob, and the Descendants, and in what was given to Moses and Jesus and to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [submitting] to Him.”
Qur’an (3:84)
Say, “O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allah. Indeed, Allah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.” And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped.
Qur’an (39:53-54)
The revelation of the Book is from Allah, the Exalted in Might, the Knowing. The forgiver of sin, acceptor of repentance, severe in punishment, owner of abundance. There is no deity except Him; to Him is the destination.
Qur’an (40:2-3)

Makes Sense, Right?

Logical Proof for God.

Righteousness is not that you turn your faces toward the east or the west, but [true] righteousness is [in] one who believes in Allah , the Last Day, the angels, the Book, and the prophets and gives wealth, in spite of love for it, to relatives, orphans, the needy, the traveler, those who ask [for help], and for freeing slaves; [and who] establishes prayer and gives zakah; [those who] fulfill their promise when they promise; and [those who] are patient in poverty and hardship and during battle. Those are the ones who have been true, and it is those who are the righteous.
Qur’an (1:177)
Allah witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise.
Qur’an (3:18)
Allah - there is no deity except Him, the Ever-Living, the Sustainer of [all] existence. Neither drowsiness overtakes Him nor sleep. To Him belongs whatever is in the heavens and whatever is on the earth. Who is it that can intercede with Him except by His permission? He knows what is [presently] before them and what will be after them, and they encompass not a thing of His knowledge except for what He wills. His Kursi [chair or knowledge] extends over the heavens and the earth, and their preservation tires Him not. And He is the Most High, the Most Great.
Qur’an (2:255)
