Sahih Muslim 705 h
'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).
وَحَدَّثَنَا ابْنُ أَبِي عُمَرَ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا عِمْرَانُ بْنُ حُدَيْرٍ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ الْعُقَيْلِيِّ، قَالَ قَالَ رَجُلٌ لاِبْنِ عَبَّاسٍ الصَّلاَةَ فَسَكَتَ ‏.‏ ثُمَّ قَالَ الصَّلاَةَ ‏.‏ فَسَكَتَ ثُمَّ قَالَ الصَّلاَةَ فَسَكَتَ ‏.‏ ثُمَّ قَالَ لاَ أُمَّ لَكَ أَتُعَلِّمُنَا بِالصَّلاَةِ وَكُنَّا نَجْمَعُ بَيْنَ الصَّلاَتَيْنِ عَلَى عَهْدِ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏
