1. It is sincere for Allah alone. [Al-Ḍaḥḥāk]
2. It is given willingly. [Muqātil]
3. It is from lawful earnings. [Ibn al-Mubārak]
4. It is given with the intention of seeking its reward from Allah.
5. It is not followed by reminders or harm (to the recipient).
6. It is given from the best of one’s wealth.
