It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) (probably as a marfu’ narration) that when he camped somewhere and liked the place, he would delay Zuhr so that he could perform a notional (surī) combination of Zuhr and Asr. And if he was traveling and did not get a chance to camp anywhere, even then he would delay Zuhr so that when he reached a place, he could perform a notional (surī) combination of Zuhr and Asr there.
