PROPHET MUHAMMAD (PBUH); A MERCY TO ORPHANS, NEEDERS, AND WIDOWS:

From his mercy is that he never used to disdain from walking along with a widow or with a poor person and fulfill their needs . He used to visit weak and sick Muslims and attend their funerals . He used to treat orphans well and charitably. He used to commend people to sponsor them and treat them with excellence and he also used to announce the consequent virtues of that saying,
“I and a patron of an orphanage are as close in Paradise (while waving with the index and middle finger and parting them .” He also said that the best house in Muslim houses is the one with an orphan being treated well in it. ” ( Bukhari and Ibn Majah)
Ibn Omar reported Allah's Messenger as saying,
"A Muslim is a Muslim's brother; he does not wrong him. If anyone cares for his brother's need, Allah will take care of his need; if anyone relieves his brother's anxiety, Allah will remove from him one of his anxieties on the Day of Resurrection; and if anyone conceals a Muslim's secrets, Allah will conceal his secrets on the Day of Resurrection." (Bukhari and Muslim)Abu Hurairah reported Allah's Messenger as saying,
‘The best house among the Muslims is one where an orphan is well treated, and the worst house among the Muslims is one where an orphan is badly treated." (Ibn Majah)Abu Omamah reported Allah's Messenger as saying, "If anyone caresses an orphan by moving his fingers in his hair, doing so only for God's sake, he will have blessings for every hair over which his hand passes and if anyone treats well ail orphan girl or boy under his care, he and I shall be like these two in Paradise," putting two of his fingers together.
