“Any Muslim who supplicates to Allah in a Du’a which contains no sin breaking of kinship, Allah will give him one of three things: either his Du`a will be immediately answered, or it will be saved for him in the Hereafter, or it will turn away an equivalent amount of evil (from him)” The companions said, “So we will ask for more.” He replied, “Allah is more [generous].”
[at-Tirmidhi, Ahmad]

Allah is He who bestows upon His creation a generosity such that were one able to comprehend the magnanimity of it, one might remain eternally paralysed from humility before such munificence.

He is the One who creates and then provides without desire or need for return. It is He who allows water to pour forth from the skies indiscriminately upon the earth to nurture it so that it may bare vegetation for the sustenance of His creation. He, Most Magnificent says, “You see the earth dry and lifeless - and [suddenly,] when We send down waters upon it, it stirs and swells and puts forth every kind of lovely plant.” (Hajj, 22: 5).

It is said that a disbeliever came to Ibrâhîm (pbuh). The disbeliever was hungry and poor so asked him for some food. Ibrâhîm (pbuh) asked the man to become a believer but he refused and so Ibrâhîm (pbuh) turned him away without granting him his request for food. Allah, Most High, rebuked Ibrâhîm (pbuh) for his behaviour saying, “I have fed this slave of Mine for sixty years, despite his disbelieving in Me, could you not feed him for a single day?” Indeed this attribute of Allah’s is one that the Muslims are taught to strive to imbibe in themselves, for Allah, al-Wahhâb, does teach, “O you who believe! Cancel not your charity by reminders of your generosity or by injury, like those who spend their substance to be seen of men, but believe neither in Allah nor in the Last Day. They are in parable like a hard, barren rock, on which is a little soil: on it falls heavy rain, which leaves it [just] a bare stone. They will be able to do nothing with aught they have earned. And Allah guides not those who reject faith.” (Baqarah, 2: 264)

Al-Wahhâb is He who responds to the prayers of His Slaves and then calls upon them to ask Him again. He, the Most Generous, says, “Call on Me; I will answer your [prayer]” (Ghâfir, 40: 40). Who can man call upon repeatedly with ever increasing demands day and night, without ever finding his requests retorted with refusal and accusations of selfishness? Indeed there is no one, but Allah. In fact the Blessed Prophet Muhammad (pbuh) informed us, “The person who does not ask from Allah, then Allah, the Exalted, becomes angry with him.”
(Tirmidhî, Ahmad)

When man gives he does so with an eye to his own benefit. Either he is embarking upon a trade in which he will see some financial return, or he is engaged in seeking reputation among the people. Even a mother, who gives herself so limitlessly to her child, does so with dreams of success and greatness for her child, which she hopes to materialise before her eyes as he grows. But al-Wahhâb bestows His gifts without seeking return, and without any diminishment of what He has, for He, Most High, has said, “O my servants, were the first of you and last of you, the human of you and jinn of you to rise up in one place and make a request from me, and were I to give everyone what they requested, that would not decrease what I have anymore than a needle decreases the sea if put into it.” (Muslim)

Let each of us ask the One who gives without restrain as He was called upon in the Qur’ânic supplication;

 “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.” (Imrân, 3: 8)
