Why should a beloved servant of Allah be burdened with trials and worries?

 By Mufti Taqi Uthmani:

The Holy  Prophet  is reported  to  have  said  in  a Hadith:

"When Allah loves some servant He showers  on him torrents of calamities and trials"

When  the  Angels  inquire  from  Allah  the  cause of  this strange treatment of His favourite servants, Allah
replies to them, saying: Let him remain in this condition,  weeping and seeking for help,  as I  like this begging  and suplications from him. This Hadith is weak in its authority but there are many Ahadith to the same effect.
According to another Hadith, Allah asks His Angels to go to His servant and entangle him  in  some trial
because  He  is  pleased  with  his  weeping  and  crying  for mercy  and  help.  The secret of this  strange treatment  of Allah with His beloved servant lies in the fact that Allah desires  to  convert  the troubles  and  trials  of His  servant into everlasting peace and comfort and elevate his status in  the  Hereafter  by  purging  him  of the  filth  of his  sins committed in the worldly life.
