- " إذا لقي أحدكم أخاه فليسلم عليه، فإن حالت بينهما شجرة أو جدار أو حجر ثم لقيه فليسلم عليه أيضا ".
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When one of you meets his brother, he should greet him with salam. If a tree, wall, or stone comes between them and then they meet again, he should greet him with salam once more."
