On the authority of Anas (may Allah be pleased with him), who said that the Messenger of Allah (peace and blessings of Allah be upon him) said:
“The gates of Paradise will be opened on Mondays and on Thursdays, and every servant [of Allah] who associates nothing with Allah will be forgiven, except for the man who has a grudge against his brother. [About them] it will be said: ‘Delay these two until they are reconciled; delay these two until they are reconciled.'”
The Prophet Muhammad (peace be upon him) said:
“O Allah, grant me life as a poor man, cause me to die as a poor man and resurrect me in the company of the poor…”
Aishah (RA) asked him why he said that, and he replied:
“Because (the poor) will enter Paradise (before) the rich. Do not turn away a poor man… even if all you can give is half a date. If you love the poor and bring them near you… Allah will bring you near Him on the Day of Ressurrection.”
[Al-Tirmidhi, Ibn-e-Majah, Ahmed]
