It was narrated from Zaid bin Thabit that he said to Marwan: “Abu ‘Abdul-Malik, do you recite: Say: He is Allah, (the) One’ and ‘Verily, We have granted you Al Kawthar’ in Maghrib?” He said: “Yes.” He (Zaid) said: “I swear by Allah, I saw the Messenger of Allah صلی اللہ علیہ وآلہ وسلم reciting the longer of the two long Surahs in it: ‘Alif-Lam Mim-Saad.” (Sahih)
