Riyad as-Salihin Hadith 507

We were once sitting in the company of Messenger of Allah (ﷺ) when a man from the Ansar came and greeted. As he was leaving, Messenger of Allah (ﷺ) said to him, "O brother of the Ansar, how is my brother Sa'd bin 'Ubadah?" He replied, "He is well." Messenger of Allah (ﷺ) asked, "Which of you is desirous of visiting him?" Having said this he got up and we followed him. We were ten and odd in number and we had neither shoes nor light boots nor caps nor shirts. We walked on foot through the barren plain till we came to the residence of Sa'd (May Allah be pleased with him). His people made way and Messenger of Allah (ﷺ) along with those who accompanied him went up to him. [Muslim].
