Whether a traveler who reaches their destination should use Rukhsahs of traveling
If a traveler arrives at his destination and does not intend to stay for a specified period or intends to stay no more than four days, it is preferable for him to offer Salah in its time shortening the four-Rak‘ah Salah (Prayer consisting of four units) without combining prayers. Yet, if he offers Salah after a resident Imam (leader in congregational Salah) who does not shorten Salah, he must offer complete Salah following his Imam. In this case, he is not permitted to abandon the congregational Salah and prays alone for shortening Salah, if he is an individual. (Part No. 6; Page No. 412) Shortening Salah is only Rukhsah (concession) while the congregational Salah is obligatory. However, if the traveler intends to stay more than four days, he must offer the Salah in full, according to the opinion of the majority of scholars, which is the correct opinion. The basic rule states that a resident has to offer complete Salah unless his stay is for four days or less. During the Farewell Hajj, the Prophet (peace be upon him) intended to stay for four days, so he shortened Salah during these days before going to
Mina. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
