“O you who have attained to faith! Fasting is ordained for you as it was ordained for those before you, so that you might remain conscious of God” [2:183]
Serve the poor.
"[The truly virtuous are] they [who] fulfil their vows, and stand in awe of a Day the woe of which is bound to spread far and wide, and who give food - however great be their own want of it - unto the needy, and the orphan, and the captive, [saying, in their hearts,] ‘We feed you for the sake of God alone: we desire no recompense from you, nor thanks: behold, we stand in awe of our Sustainer’s judgment1 on a distressful, fateful Day!’" [76:7-10]
Be nicer to your parents.
Be more patient with your siblings.
"And worship God [alone], and do not ascribe divinity, in any way, to aught beside Him. And do good unto your parents, and near of kin, and unto orphans, and the needy, and the neighbour from among your own people, and the neighbour who is a stranger, and the friend by your side, and the wayfarer, and those whom you rightfully possess. Verily, God does not love any of those who, full of self-conceit, act in a boastful manner;” [4:36]
Finally, to sum it all up, The Prophet is reported to have said in Sahih Muslim and in Imam Nawawi’s collection the following:
"Whoever removes a worldly grief from a believer, God will remove from him one of the griefs of the Day of Resurrection. And whoever alleviates the need of a needy person, God will alleviate his needs in this world and the Hereafter. Whoever shields [or hides the misdeeds of] a Muslim, God will shield him in this world and the Hereafter. And God will aid His slave so long as he aids his brother. And whoever follows a path to seek knowledge therein, God will make easy for him a path to Paradise. No people gather together in one of the Houses of God, reciting the Book of God and studying it among themselves, except that sakeenah (tranquility) descends upon them, and mercy envelops them, and the angels surround them, and God mentions them amongst those who are with Him. And whoever is slowed down by his actions, will not be hastened forward by his lineage."
