It was narrated from Ibn 'Abbas that he prayed Al-Uula (Zuhr) and 'Asr together in Al-Basrah with nothing in between them, and he prayed Maghrib and 'Isha' together with nothing in between them. He did that because he was busy and Ibn 'Abbas said that he had prayed Zuhr and 'Isha' together with the Messenger of Allah (ﷺ) in Al-Madinah, eight Rak'ahs with nothing in between
Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Our source also lists this ruling under Abu Ghuddah, the editor of the printed edition it was taken from. It is al-Albani's ruling printed again, so it is counted once.
