Jabir b. Samura said that the Prophet used to recite in the sunset prayer on Thursday evening, “Say, O unbelievers,”1 and “Say, He is God one God.”2
1. Al-Qur’an; 109
2. Al-Qur’an; 112
[Baghawi] transmitted it in Sharh as-sunna; and Ibn Majah transmitted it from Ibn ‘Umar, but did not mention Thursday evening.
