Sunan an-Nasa'i, Volume 1, Book 6, Hadith 589 (DarusSalam) ⓘ

Kathir bin Qarawanda said: "I asked Salim bin 'Abdullah about how his father prayed when traveling. We asked him: 'Did he combine any of his prayers when traveling?' He said that Safiyyah bint Abi 'Ubaid was married to him, and she wrote to him, when he was at some farmland of his, saying: 'This is the last of my days in this world, and the first day of the Hereafter." [1] He rode quickly to go to her, and when the time for Zuhr came, the Mu'adhdhin said to him: "The prayer, O Abu 'Abdur-Rahman!" But he paid no attention to him until it was between the time for the two prayers, then he stopped and said: "Say the Iqamah and when I say the Taslim, say the Iqamah." Then he rode on again, and when the sun set the Mu'adhdhin said to him; "The prayer!" He said: "Do as you did for Zuhr and 'Asr." When the stars had appeared, he stopped and said to the Mu'adhdhin: "Say the Iqamah and when I say the Taslim, say the Iqamah." He prayed, then when he had finished he turned to us and said: "The Messenger of Allah said: 'If any one of you has an urgent need that he fears he may miss, let him pray like this.'" [1] Meaning that she was dying.
