In verse I have recited, our Lord Almighty (SWT) states as follows, “And spend [in the way of Allah ] from what We have provided you before death approaches one of you and he says, ‘My Lord if only You would delay me for a brief term so I would give charity and be among the righteous.’” 
In the hadith I have read, the Prophet Muhammad (saw) informs us that Allah the Almighty (SWT) states as follows, “O, Children of Adam, Spend (on charity), and I shall spend on you.” 
Infaq means to offer to other people from the property and wealth and from the blessings Allah (SWT) has entrusted to us. It means to protect, observe, and guard those in need. It means to strive to be useful to our family, relatives, neighbors, brothers, and sisters, and, in short, all humanity.
Infaq leads to the rehabilitation of the body and soul. We purify our nafs and property with infaq. With infaq, we share our sorrow and suffering, thereby attaining the pleasure of Allah (SWT).
Infaq leads to the rehabilitation of society as well. It reinforces the harmony, peace, unity, and solidarity between us and our brothers and sisters. Helping and being there for our brothers and sisters become widespread with infaq.
It is stated in the Holy Qur’an as follows, “And from their properties was [given] the right of the [needy] petitioner and the deprived.” 
Then, let us, with peace of heart, let our brothers and sisters enjoy their rights over us. Let us support the poor, the needy, the orphan, and then the abandoned. Let us try to solve the problems of primarily our relatives and neighbors, and all those in need, with fitrah and zakat. Let us not forget that never will we attain the good [reward] until we spend [in the way of Allah] from that we love.
