Sayyidah Aishah al-Siddiqah (may Allah be pleased with her) narrated: During a journey the Prophet (peace and blessings be upon him) would delay the Zuhr prayer and offer the Asr prayer early, and he would delay the Maghrib prayer and offer the Isha prayer early.
Imam Ahmad recorded it; its chain contains a narrator, Mughirah bin Ziyad, whom Yahya bin Ma'in, Ibn Adi and Abu Zur'ah declared thiqah (trustworthy), while Imam Bukhari (may Allah have mercy on him) and others declared him da'if (weak).
