Mukhtasar Bukhari

Narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that a Bedouin asked the Messenger of Allah (peace and blessings of Allah be upon him) about migration. The Prophet (peace and blessings of Allah be upon him) said: "Woe to you, the matter of migration is very difficult. Do you have some camels from which you give zakat?" He replied, "Yes." The Prophet (peace and blessings of Allah be upon him) said: "(Then you do not need to migrate) Worship even across the rivers (i.e., in your own land), for Allah will not let any of your worship go to waste."
