The most beloved of people to Allah is he who brings most benefit to people

The Prophet (peace be upon him) said:

أحب الناس إلى الله أنفعهم و أحب الأعمال إلى الله عز و جل سرور تدخله على مسلم أو تكشف عنه كربة أو تقضي عنه دينا أو تطرد عنه جوعا و لأن أمشي مع أخي المسلم في حاجة أحب إلي من أن أعتكف في المسجد شهرا و من كف غضبه ستر الله عورته و من كظم غيظا و لو شاء أن يمضيه أمضاه ملأ الله قلبه رضى يوم القيامة و من مشى مع أخيه المسلم في حاجته حتى يثبتها له أثبت الله تعالى قدمه يوم تزل الأقدام و إن سوء الخلق ليفسد العمل كما يفسد الخل العسل

“The most beloved of people to Allah is he who brings most benefit to people, and the most beloved of deeds to Allah the Mighty, the Magnificent, is that you bring happiness to a fellow Muslim, or relieve him of distress, or pay off his debt or stave away hunger from him. It is more beloved to me that I walk with my brother Muslim in his time of need than I stay secluded in the mosque for a month.Whoever holds back his anger, Allah will cover his faults and whoever suppresses his fury while being able to execute it, Allah will fill his heart with satisfaction on the day of judgement. Whoever walks with his brother Muslim in need until he establishes that for him, Allah will establish his feet firmly on the day when all feet shall slip. Indeed, bad character ruins deeds just as vinegar ruins honey."
