The Muslim who understands his religion is tolerant in his dealings with people, because he knows that there is nothing like tolerance for the good man in this world and the next. His tolerant, gentle, easygoing attitude opens the way to people’s hearts, and endears him to them, and it also earns him Allah’s pleasure, forgiveness and mercy. This is what is stated clearly in the teachings of the Prophet (sallallahu `alayhi wa sallam).
Jabir (radhiallahu `anhu) reported that the Prophet (sallallahu `alayhi wa sallam) said:
“May Allah (subhanahu wa ta`ala) have mercy on the tolerant man, when he buys, when he sells, and when he demands payment.” (Bukhari)
Abu Mas’ud al-Ansari said:
“The Prophet (sallallahu `alayhi wa sallam) said: ‘A man from those who were before you was brought to account and no goodness was found in him, except that he was a man who used to mix with people; he was rich, and he used to order his employees to let off the one who was in difficulty. Allah (subhanahu wa ta`ala) said: “We should be even more tolerant than him, so let him off.’” (Muslim)
How heavily this attitude will weigh in the balance, and how much will man need it on that great and terrible Day
