Ibn Rajab stated:
“Patience is of three types.
1. Patience in obeying Allah.
2. Patience in refraining from that which Allah has prohibited,
3. Patience in accepting the decree of Allah when it is hurtful.
All three types of patience are combined in fasting.”

“…Only those who are patient shall receive their reward in full, without reckoning.”
