Hawzah News Agency – The Prophet (SAWA), when he passed by a grave wherein someone had been buried the day before, and the person's family was crying over the grave, said,

لَرَكعَتانِ خَفيفَتانِ ممّا تَحتَقِرُونَ أحَبُّ إلى‏ صاحِبِ هذا القَبرِ مِن دُنياكُم كُلِّها.

'Two simple units of prayer that you deem insignificant are dearer to the person in this grave than the whole of your world.'
