Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, "If Allah wills good for someone, He afflicts him/her with trials."
And if Allah loves someone He calls Gabriel (the angel) and says: I love so-and-so, so you love him. Gabriel loves him, and calls the other angels in Heaven to love that person. They love him, then his love will be made upon earth, and he becomes loved.
