Anas bin Malik reported,

The Prophet ﷺ said to Abu Talha, "Find me a boy from among your servants to attend to me while I set out for Khaybar."So Abu Talha took me out riding behind him. I was a boy approaching puberty. I would serve the Messenger of Allah ﷺ whenever he stopped to rest, and I often heard him say, "O Allah, I seek refuge in You from anxiety and grief, from helplessness and laziness, from miserliness and cowardice, from the burden of debt and from being overpowered by men."Then we arrived at Khaybar. When Allah granted him victory over the fortress, the beauty of Safiya bint Huyayy bin Akhtab was mentioned to him. Her husband had been killed, and she was a new bride. The Messenger of Allah ﷺ chose her for himself and set out with her. When we reached Sadd al-Sahba, she became permissible for him, and he consummated the marriage with her. Then he prepared hays on a small leather mat and said, "Invite those around you."That was the wedding feast of the Messenger of Allah ﷺ for Safiya. Then we set out for Medina.I saw the Messenger of Allah ﷺ folding a cloak behind him for her, then he would sit beside his camel and place his knee down so that Safiya could put her foot on his knee to mount.We continued on until we came in sight of Medina. He looked toward Uhud and said, "This is a mountain that loves us and we love it." Then he looked toward Medina and said, "O Allah, I declare sacred what lies between its two lava fields, just as Ibrahim declared Mecca sacred. O Allah, bless them in their mudd and their saa."

حدثنا قتيبة حدثنا يعقوب عن عمرو

عن أنس بن مالك رضي الله عنه

أن النبي ﷺ قال لأبي طلحة التمس غلاما من غلمانكم يخدمني حتى أخرج إلى خيبر فخرج بي أبو طلحة مردفي وأنا غلام راهقت الحلم فكنت أخدم رسول الله ﷺ إذا نزل فكنت أسمعه كثيرا يقول اللهم إني أعوذ بك من الهم والحزن والعجز والكسل والبخل والجبن وضلع الدين وغلبة الرجال ثم قدمنا خيبر فلما فتح الله عليه الحصن ذكر له جمال صفية بنت حيي بن أخطب وقد قتل زوجها وكانت عروسا فاصطفاها رسول الله ﷺ لنفسه فخرج بها حتى بلغنا سد الصهباء حلت فبنى بها ثم صنع حيسا في نطع صغير ثم قال رسول الله ﷺ آذن من حولك فكانت تلك وليمة رسول الله ﷺ على صفية ثم خرجنا إلى المدينة قال فرأيت رسول الله ﷺ يحوي لها وراءه بعباءة ثم يجلس عند بعيره فيضع ركبته فتضع صفية رجلها على ركبته حتى تركب فسرنا حتى إذا أشرفنا على المدينة نظر إلى أحد فقال هذا جبل يحبنا ونحبه ثم نظر إلى المدينة فقال اللهم إني أحرم ما بين لابتيها بمثل ما حرم إبراهيم مكة اللهم بارك لهم في مدهم وصاعهم
