The Prophet Mohammad peace be be with always extended love, mercy and forgivness to all those with him and against him. Here is an incident when he reminds fellow Muslims that the hereafter is the better life, as well wishes for Allah's forgivness
Sahl bin Sa'd As-Sa'idi narrated, "We were in the company of Allah's Apostle salallahu alayhi wasallam in (the battle of) Al-Khandaq, and he was digging the trench while we were carrying the earth away. He looked at us and said, "O Allah! There is no life worth living except the life of the Hereafter, so (please) forgive the Ansar and the Emigrants."
(Bukhari, Book 76, Volume 8, Hadith 423)
