From Sahih Muslim (Hadith 1637):
Abdullah b. Shaqiq al-'Uqaili reported:A person said to Ibn 'Abbas (as he delayed the prayer): Prayer. He kept silence. He again said: Prayer. He again kept silence, and he again cried: Prayer. He again kept silence and said: May you be deprived of your mother, do you teach us about prayer? We used to combine two prayers during the life of the Messenger of Allah (ﷺ)
