Shaykhul-Islam Ibn Taymiyyah (rahimahullaah) said:
“…And the slave – the more humble, needy, and subdued he is before Allah – the closer he will be to Him, and the dearer he will be to Him, and the greater in status he will be to Him.
So, the happiest of the Creation is the one who is greatest in servitude to Allah.
As for the Creation, as it is said:
Be in need of whoever you wish, and you will be his prisoner; be sufficient from whoever you wish, and you will be his adversary; be kind to whoever you wish, and you will be his authority…
So, the greatest in status and honor the slave is with others is when he is not in need of them in any way, shape, or form. If you are good to others while not being in need of them, you will be greater in their eyes. When you are in need of them – even if for a sip of water – your status is reduced in their eyes in accordance with what it is you need from them. And this is from the Wisdom and Mercy of Allah, in order that the Religion all be for Allah, and that nothing be associated with Him.
Because of this, when Hatim al-Asam was asked: ‘With what can one protect himself from people?’
“That you freely give them from what you have, and that you are cold and indifferent towards what they have.”
However, if you are in a position to be compensated from them, and they are also in need of something from you, and the needs of the two sides become equal, you become like two merchants, none of whom has any virtue over the other. If they are the more needy side, that is when they will become subdued.
So, with the Exalted Lord, the most generous you are to Him is when you are most in need of Him.With the Creation, the most insignificant you are to them is when you are most in need of them…”
