One who acknowledges the virtue of an old man and honours him for his age, God will save him from the fright of the Day of Resurrection. Honouring a Muslim with white hair partakes in Glorifying the Majesty of God. (hadith)
To make one good action succeed another, is the perfection of goodness (Sayyidina Ali ibn Abi Talib).
Humour Without Malice
A men fell on the ground, and soon after fell down again. He said to himself: "Had I known I was going to fall a second time, I would have not gotten up so soon."
