prophet (s.a.w)

The Prophet ﷺ said: “The most beloved people to Allah (swt) are those who help and benefit others the most, and the most beloved actions to Allah (swt), is pleasure and happiness that you cause to enter the heart of a Muslim, or to solve one of his problems, or to pay off his debt, or to prevent him from being hungry, and working to help my Muslim brother is more beloved to me than making I’tikaf in this masjid for a month, and whoever controls his anger, Allah will conceal his faults, and whoever controls his ill feelings, Allah (swt) will fill his heart with contentment on the day of Judgment, and whoever strives to help fulfill a need for his Muslim brother, Allah will make his feet steadfast on the day of Judgment, and bad manners ruin good deeds just like vinegar ruins honey.”
—  (Sheikh Al-Albani said it is a sound hadith)
There are three things for which whomever has them, then he has tasted the sweetness of faith: 1. The one for whom Allah and His Messenger are more beloved than anything else; 2. Whoever loves someone and he does not love him except for the sake of Allah; 3. Whoever hates to return to disbelief after Allah has saved him from it, just as he hates to be thrown into fire.
