Imam Abu Bakr, may Allah have mercy on him, says that this hadith of Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, performed four rak'ahs of Zuhr prayer in Madinah Munawwarah and performed two rak'ahs of Asr prayer at the place of Dhul-Hulaifah. This is evidence that even in a state of peace and security, without fear of the mischief of the disbelievers, a person performing prayer (while traveling) can shorten the prayer.
