If everyone takes care of, educates, provides for and prioritizes their families and themselves, an ideal society will certainly be formed.
If so, then there is no need for tabarru contract, no need for alms, no need for waqf, no need for zakat, hawalah, kafalah etc., all of which exist in the world, in fact the concept given by Islam is SALING.
Yes! Give each other, advise each other, reprimand each other, fill each other, love each other, help each other even commercial contracts exchange (buying and selling).
The difference is that there is no need to bargain, there is no need to expect reciprocity, there is no need for appropriate or inappropriate exchanges. There is no need for calculations etc., on the contrary, commercial contracts must be something valuable, valuable, useful in exchange for something valuable, valuable, useful as well.
"For the sake of time, indeed men are at a loss, except those who believe and work virtue and exhort one another for truth and exhort one another for patience" (Al-Asr: 1-3).
With the concept of mutual care, it is not allowed to hurt, persecute, ignore, and selfish. It is not permissible if only oneself is full, the profitable, the great, the prosperous, the strong, nor should he twist the word SALING into hurting each other, wronging each other, ignoring each other etc.
The Companions of the Prophet who knew the Qur'an and Hadith very well, in fact had a generous soul, an unselfish nature, an attitude that always wanted to give the best they had for others.
"One of you has no faith until he loves his brother as he loves himself." (Narrated by Bukhari and Muslim)
What became terrible then the Companions of the Messenger of Allah also did not want to burden others, mahsyur said Abdurahman bin Auf Radhiyallahuanhu during the Hijra and would be given half a property assistance by an Anshor of Medina:
"I am the richest man of the Ansars. I will divide half of my treasure to you. I also have two wives so choose which one appeals to you the most among them. Say the name, then I will reject it. If the Idahnya is finished, marry her," he said.
The offer was gently rejected by Abdurrahman. He said.
"May Allah bless you upon your family and property,"
"It is enough for you to show me where your market is," said Abdurahman bin Auf Radhiyallahuanhu.
This is a form of mutual respect, mutual respect, mutual appreciation, mutual reluctance, mutual understanding, mutual understanding, without any negative frills.
An attitude that is difficult to find today, where many people actually use verses and arguments to prioritize themselves and their own families, their own children, their own parents while ignoring others, because they feel only responsible for their own families and not responsible for the circumstances of others, except with appropriate retribution.
Naudzubillah min dzalik.
