Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Whoever gives charity from his lawful earnings—and Allah accepts only that which is lawful—it is as if he placed (that charity) in the palm of the Most Merciful. Then Allah nurtures it for one of you, just as one of you raises his young animal, until it (the charity) becomes like the mountain of Uhud.”

Brief Explanation
(Commentary on Hadith 1712)
The meaning of this hadith is that even if lawful (halal) wealth is very little, and a Muslim gives it in charity (sadaqah) in the way of Allah, its reward is immense, which continues to increase in the sight of Allah Ta'ala, until its reward becomes as great as a mountain.
In the narrations of the Sahihayn, it is mentioned that the Lord of the worlds accepts it with His right hand. From this and the aforementioned hadith, the affirmation of Allah Ta'ala’s hand and pouch is established.
The position of the Ahl al-Hadith school is that the attributes of Allah Ta'ala are true; it is obligatory to have faith in them, but likening (tashbih) and comparison (tamthil) are not permissible. Allah, the Exalted, has hands, but how they are is unknown to anyone, and they are not like our hands or pouch.
