It is He who has sent to the unlettered people an apostle from among themselves, reciting to them and teaching them the Book and wisdom, although they were before in manifest error. (Qur'an, 62:2)
The Noble Messenger of Allah (s.a.w.) said:
"Never does he believe in me who goes to bed full while his neighbour is hungry. Never shall Allah on the Day of Judgement look with favour at the people of a place who pass their night satisfied but among them is a hungry one."
Imam Ali (a. s.) said :
The tongue is like a lion -- if you let it run free, it will wound someone
Imam Ja'far al-Sadiq (a.s.) said:
"The right of the Muslim on the Muslim is that he should never eat his fill while his brother suffers, never should be quench his thirst while his brother suffers thirst, never should he clothe himself while his brother suffers inadequate clothing."
There are six kinds of people who will not be able to avoid sorrow:
poor people who have newly acquired wealth;
rich people who fear for the safety of their wealth;
people who seek positions which are beyond their capacity;
people who are envious;
people who are full of malice; and
people who mix with the people of courteous behaviour when they do not behave courteously themselves.
Being ignorant of excellence is tantamount to being dead.
There are three things which cause ruin:
pride, for surely it caused the downfall of Satan from his high station; and
greed, for surely it caused Adam to be expelled from the Garden; and
envy, for surely it induced the son of Adam to kill his brother.
There are four things of which even a little is too much: fire, enmity, illness and poverty.
There is nothing more ugly than
breaking off relations after establishing them, and
treating people harshly after being like a brother to them, and
being an enemy after being a friend, and
being dishonest towards anyone who has put his trust in you, and
betraying anyone who has submitted himself to you.
