It was narrated that Ibn 'Abdur-Rahman said:
"A man became Junub and came to 'Umar, may Allah be pleased with him, and said: 'I have become Junub and I cannot find any water.' He said: 'Do not pray.' 'Ammar said to him: 'Do you not remember when we were on a campaign and became Junub. You did not prayed, then I came to the Prophet (ﷺ) and told him that, and he said: 'This would have been sufficient for you.'" - (One of the narrators) Shu'bah struck his hands once and blew into them, then he rubbed them together, then wiped his face with them - ('Ammar said): "'Umar said something I did not understand." So he said: "If you wish, I shall not narrate it." Salamah mentioned something in this chain from Abu Malik, and Salamah added that he said: "Rather, we will let you bear the burden of what you tool upon yourself." (ES)
