A traveler offers Salah behind a resident Imam

Q: If I was a traveler and I entered one of the Masjids (mosques) in Madinah and I was made an Imam (the one who leads congregational Prayer) for resident Ma’mums (people being led by an Imam in Prayer), should I offer shortened or complete Salah during Zhuhr (Noon) Prayer, ‘Asr (Afternoon) Prayer or ‘Isha’ (Night) Prayer?

A: It is permissible for you to lead them in Salah, but you have to inform them that you are going to shorten Salah (Prayer) in order that they complete their Salah after you finish your Salah just as the Prophet (peace be upon him) did with the people of Makkah on the Conquest of Makkah; and if you complete the Salah you are leading them in, there is nothing wrong in this.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
