There are many relevant Hadīths previously cited, like the one that reads: “Allah helps a person as long as he helps his brother.”
And like the Hadīth: “Every act of kindness is charity,” and similar Hadīths.
969/1 - Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported: While we were with the Messenger of Allah (may Allah’s peace and blessings be upon him) on a journey, a man came on his mount and starting looking right and left. Thereupon, the Prophet said: “He who has an extra mount should give that to one who has no mount, and he who has surplus of provisions should give them to one who has no provisions.” He made mention of so many kinds of wealth until we started to think that none of us had any right to any surplus. [Narrated by Muslim]
970/3 - Jābir (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) decided to embark on an expedition, so he said: “O group of Muhājirūn and Ansār, there are among you those who have no property and no kinsfolk. So let each one of you take along with him two or three men, for none of us has a spare animal and we ride by turns.” So I took two or three men with me and I rode my camel by turns with them. [Narrated by Abu Dāwūd]

3) He who takes charge of people’s education should treat them gently and notice the weak and the disabled among them.
