Wot is true love?

Hi. 11/12/17 where do u think we hav learnt to luv so honestly, quietly & deeply? mashallah from our mentor n beloved prophet mohammad pbuh himself. how? in reciproct of prophet mohammads unselfish acts for us since the inception of his prophethood until the day he breathed his last breath. many nites he wud pray all nite standing up & crying to allah. he repeatedly kept saying ya ummati with his supplications to get reassurance from allah that he  won't put nabi's ummats under hard tests. more then 1400 years back he prayed for all his ummats that will b born up until kiamah, which  includes us the current ummah, none of whom he had ever seen.  yet, father of the ummah kept crying to his creator not for himself but for the future ummats welfares. during the very long prayer sessions he did not even notice his legs had swollen from standing for too long & his beautiful long beard so wet from his tears that they looked like after bath drenched beards.
