Patience

"The best kind of patience is fasting, for it combines all 3 types of patience. It is patience in obeying Allah, may He be glorified & exalted, & it is patience in refraining from disobeying Him, because a person gives up his desires for the sake of Allah even though his self may be longing for them...Fasting also involves patience in accepting the consequences which may result in hunger & thirst for the fasting person."

[Ibn Rajab al-Hanbali (may Allah have mercy on him)]
