Ayat 85. They said: "In Allah we put our trust. Our Lord! Make us not a trial for the folk who are Zalimun (polytheists and wrong-doing) (i.e. do not make them overpower us).
Ayat 87. And We inspired Musa (Moses) and his brother (saying): "Take dwellings for your people in Egypt, and make your dwellings as places for your worship, and perform As-Salat (Iqamat-as-Salat), and give glad tidings to the believers."
Hazrat Abu Umamah (May Allah be pleased with him) said: I heard Messenger of Allah [SAWW](PBUH) during the sermon of the Farewell Pilgrimage saying, "Be mindful of your duty to Allah; perform your five daily Salat, observe Saum during the month (of Ramadan), pay the Zakat on your properties and obey your leaders; (if you do so) you will enter the Jannah of your Rubb". [At-Tirmidhi Hadith # 616].
Lesson : as mentioned above in Surah Yunus Ayat 87. "and make your dwellings as places for your worship, and perform As-Salat (Iqamat-as-Salat), " This Hadith brings out the following point: The word Wada`, means to say farewell. The Farewell Pilgrimage was the last pilgrimage, the Prophet (PBUH) performed, and on this occasion he bade farewell to the people and for this reason it came to be known as Hajjat-ul-Wada`. Obedience of the rulers is stressed but it is conditional, that is to say, they are to be obeyed only if their orders are not against the injunctions of Allah. Similarly, their obedience is obligatory till such time that they do not do anything which amounts to open disbelief. If any of these two things occurs, then no obedience would be due to them.
