It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: A Muslim has six rights over another Muslim in the form of goodness: when he meets him, he should greet him with Salam; when he sneezes, he should say "Yarhamukallah" (may Allah have mercy on you); when he falls ill, he should visit him; when he invites him, he should accept; when he passes away, he should participate in his funeral prayer; whatever he likes for himself, he should like for him as well, and in his absence, he should wish well for him.

It is narrated from Sayyiduna ‘Ubada bin Samit (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) said: Guarantee me six things and I will guarantee you Paradise: (1) When you speak, speak the truth; (2) When you make a promise, fulfill it; (3) When something is entrusted to you, return it; (4) Guard your private parts; (5) Lower your gaze; (6) And restrain your hands.

Narrated from Sayyiduna Khuraim bin Fatik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Deeds are six and people are four. Two are obligatory, two are equal, one good deed is tenfold, and one good deed is seven hundredfold. The two obligatory are these: Whoever dies in such a state that he does not associate partners with Allah, will enter Paradise; and whoever dies in such a state that he associates partners with Allah, will enter Hell. The two equal are these: Whoever intends to do a good deed so much that his heart understands it and Allah knows it, one good deed will be written for him; and whoever commits an evil deed, only one evil deed will be written for him. Whoever does a good deed, its reward will be tenfold; whoever spends in the way of Allah and does a good deed, its reward will be seven hundredfold. As for the matter of people: Whoever is given abundance in this world, will have constriction in the Hereafter; whoever is given constriction in this world, will have abundance in the Hereafter; and some are such that abundance will be chosen for them in both this world and the Hereafter.
