Friendship of a lifetime

My dad and my father-in-law have been friends since they attended school in Madeenah munawarah ages ago,then they married two sisters which made their relationship even stronger ,then a couple their children married, resulting in having joint grandkids....to make a long story short ,these faithful brothers stayed in touch and with old age it was hard for them to see each other that often-one living in theEast and the other in the West!!
So my dad being the younger of the two decided to pay his brother (who was suffering from a stroke lately)a surprise visit....

Mashallah between them they have four grandchildren and four great-grandchildren and of course each has more grandchildren from their other off-spring!!
