Allah reminds His believing servants with what He has endowed them with by sending Muhammad as a Messenger to them, reciting to them Allah's clear Ayat and purifying and cleansing them from the worst types of behavior, the ills of the souls and the acts of Jahiliyyah (pre-Islamic era). The Messenger also takes them away from the darkness (of disbelief) to the light (of faith) and teaches them the Book, the Qur'an, and the Hikmah (i.e., the wisdom), which is his Sunnah. He also teaches them what they knew not. During the time of Jahiliyyah, they used to utter foolish statements. Later on, and with the blessing of the Prophet's Message and the goodness of his prophecy, they were elevated to the status of the Awliya' (loyal friends of Allah) and the rank of the scholars. Hence, they acquired the deepest knowledge among the people, the most pious hearts, and the most truthful tongues. Allah said:

(Indeed, Allah conferred a great favor on the believers when He sent among them a Messenger (Muhammad) from among themselves, reciting unto them His verses (the Qur'an), and purifying them (from sins).) (3:164)

Allah also criticized those who did not give this bounty its due consideration, when He said:

(Have you not seen those who have changed the favors of Allah into disbelief (by denying Prophet Muhammad) and his Message of Islam), and caused their people to dwell in the house of destruction) (14:28)

Ibn `Abbas commented, "Allah's favor means Muhammad.'' Therefore, Allah has commanded the believers to affirm this favor and to appreciate it by thanking and remembering Him:

(Therefore, remember Me. I will remember you, and be grateful to Me, and never be ungrateful to Me.)

Mujahid said that Allah's statement:

(Similarly (to complete My favor on you), We have sent among you a Messenger (Muhammad) of your own,)

means: Therefore, remember Me in gratitude to My favor.

Al-Hasan Al-Basri commented about Allah's statement:

(Therefore remember Me. I will remember you), "Remember Me regarding what I have commanded you and I will remember you regarding what I have compelled Myself to do for your benefit (i.e., His rewards and forgiveness).''

An authentic Hadith states:

(Allah the Exalted said, `Whoever mentions Me to himself, then I will mention him to Myself; and whoever mentions Me in a gathering, I will mention him in a better gathering.)'

Imam Ahmad reported that Anas narrated that Allah's Messenger said:

(Allah the Exalted said, `O son of Adam! If you mention Me to yourself, I will mention you to Myself. If you mention Me in a gathering, I will mention you in a gathering of the angels (or said in a better gathering). If you draw closer to Me by a hand span, I will draw closer to you by forearm's length. If you draw closer to Me by a forearm's length, I will draw closer to you by an arm's length. And if you come to Me walking, I will come to you running).

Its chain is Sahih, it was recorded by Al-Bukhari. Allah said:

(...and be grateful to Me (for My countless favors on you) and never be ungrateful to Me.)

In this Ayah, Allah commands that He be thanked and appreciated, and promises even more rewards for thanking Him. Allah said in another Ayah:

(And (remember) when your Lord proclaimed: "If you give thanks (by accepting faith and worshipping none but Allah), I will give you more (of My blessings); but if you are thankless (i.e., disbelievers), verily, My punishment is indeed severe.)

Abu Raja' Al-`Utaridi said: `Imran bin Husayn came by us once wearing a nice silken garment that we never saw him wear before or afterwards. He said, "Allah's Messenger said:

(Those whom Allah has favored with a bounty, then Allah likes to see the effect of His bounty on His creation), or he said, "on His servant'' - according to Ruh (one of the narrators of the Hadith).

(153. O you who believe! Seek help in patience and As-Salah (the prayer). Truly, Allah is with As-Sabirin (the patient).) (154. And say not of those who are killed in the way of Allah, "They are dead.'' Nay, they are living, but you perceive (it) not.)
