Hazrat Abu Huraira رضی اللہ عنہا narrates that the Holy Prophet ﷺ said: “A person proceeded on a journey to a town to meet a Muslim brother. Allah Almighty placed an angel on the route, When that person reached near the angel, the angel asked: ‘Where do you intend going?’ The man replied: ‘ I am going to meet a brother who lives in this town.’ The angel enquired: ‘Do you have any right on the person you are proceeding to meet with?’ He answered: ‘No, But I am going to see him as I love him for the sake of Allah.’ The angel said: ‘Allah has sent me here to tell you that the way you love this brother only for Allah’s sake, Allah also loves you the same way.” (Muslim) 

It is related to Hazrat Abu Huraira رضی اللہ عنہا that the Holy Prophet ﷺ said: “It is prohibited for a believer that he disaffiliates himself from a brother Muslim for more than three days. Therefore if three days have passed, he should meet the brother and greet him with Salam. If he replies to the Salam, both of them will earn the blessings. If he does not respond, he will remain to be a sinner and the other one will be exonerated from the sin of disaffiliation.”  (Abu Daud) 

Hazrat Jabir رضی اللہ عنہا narrates that the Holy Prophet ﷺ said: “If a Muslim grows a tree,  and when a portion of it is consumed, it becomes a Sadqa (charity in the name of Allah) for the grower. And the portion which is stolen also becomes a Sadqa, meaning that the owner earns the blessings of a Sadqa. And whatever part of that tress is eaten by birds, also becomes a Sadqa for the owner. In short, anyone who takes something from that tree (like fruit etc.), it becomes Sadqa for the grower of that tree.” (Muslim)
