Hadrath Umer bin Abdul Azeez (R.A) was the Caliph of Muslims .He was exceedingly pious and simplicity was the hall mark of his character.
One day a visitor came to him when he was engaged in writing something in the light of the lamp .By chance the oil in the lamp had almost exhausted .After a while the lamp flickered and then went out .The guest then said :’ “You do not worry ,I will put it right.” Thereupon the Caliph said: It is improper to ‘ take service from guests “
Then the guest suggested : “Well ,then I will wake up the servant and he will put it right”.
“No. No. Do not wake up the poor fellow .He has just now gone to sleep H e would be unnecessarily put to trouble .” So saying ,the Caliph himself got up ,put oil in the lamp and brought it back. “After all you took the trouble yourself,”said the guest.
The Caliph repiied : “So what ? Where is the question of trouble in it? When I went to put oil in the lamp I was Umer ,and when I have returned ,then too, Iam the same Umer,”
With this answer the guest was rendered speechless.
