‘Imran bin Hudair said: “I asked Láhiq about the two Rak’ahs before sunset. He said: “Abdullah bin Az-Zubair used to pray them, and Muawiyah sent word to him asking: ‘What are these two Rak’ahs at sunset?’ He had to refer to Umm
Salamah, and Umm Salamah said: The Messenger of Allah صلی اللہ علیہ وآلہ وسلم used to pray two Rak’ahs before ‘Asr, then he was distracted and did not pray them, so he prayed them when the sun set, and I never saw him pray them before or after that.” (Sahih)
