After Allah swt describes the qualities of the believer regarding prayers in topic "God-fearing Believers" above, He now explains the God-Fearing believers in regards to Charity
And in their wealth there was the right
a designated part which they dedicated to the Sa'il and Mahrum
Sa'il is the poor who begs others, and he has due right
As for Mahrum, Ibn `Abbas and Mujahid said, "He is the poor person who does not receive a stipend." Meaning he does not receive a stipend from the Muslim treasury, nor does he have a means of income, nor a profession. The Mother of the faithful, `A'ishah may Allah be pleased with her, said about the Mahrum, "He is the displaced, the one who does not have a profession to easily earn an income from." Qatadah and Az-Zuhri: "The Mahrum is the one who does not ask the people for anything." Az-Zuhri added that the Messenger of Allah ﷺ said,
(The poor (Miskin) is not the one who goes round to the people and asks them for a mouthful or two or a date or two. But the poor is the one who does not have enough to satisfy his needs and whose condition is not known to others, so that others may give him something in charity.)
And on the earth are signs for those who have faith with certainty
Allah says that there are signs on earth that testify to the might of the Creator and His boundless ability. These signs include what Allah placed on the earth, the various plants, animals, valleys, mountains, deserts, rivers and oceans. He also created mankind with different languages, colors, intentions and abilities, and a variety among them, differences in the power of understanding and comprehension, their deeds, and ultimately earning happiness or misery. Allah put every organ in their bodies in its rightful place where they most need it to be.
And also in yourselves. Will you not then see
Qatadah explains, " "He who thinks about his own creation will realize that he was created with flexible joints so that it is easy for him to perform acts of worship."
And in the heaven is your provision
which means rain
And that which you are pronised
Ibn 'Abbas, Mujahid and several others said it means Paradise
Then Allah swt says
Allah is swearing by His honorable Self, all of the matters of the Judgement, Resurrection, and Recompense that they have been promised shall certainly occur. Therefore, it is the truth, there being no doubt about it, so do not doubt its coming, just as you do not doubt that you can speak When he would talk to one of his friends, Mu`adh used to say: "What I am saying is as true as you are being here."
