Sayyiduna Sahl bin Mu'adh narrates from his father (may Allah be pleased with him), and he from the Messenger of Allah (peace and blessings be upon him), that he (peace and blessings be upon him) said: "To see off a mujahid in the path of Allah and help him onto his mount, in the morning or the evening, is dearer to me than the world and all that is in it." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) sent (a detachment of the Companions) off, he walked with them as far as Baqi' al-Gharqad, then said: "Set off in the name of Allah. O Allah, help them." Imam Bukhari used Thawr bin Yazid and Ikrimah as evidence, and Imam Muslim used Muhammad bin Ishaq, and this is a gharib (singular) sahih (authentic) hadith, but the two Shaykhs (Bukhari and Muslim) did not record it.
