This is one of the greatest proofs that Allaah alone is worthy of worship, for verily He is the One who grants benefit or harm, the One who provides and the One who prevents.
If
any harm such as poverty and sickness etc. befalls you ‘there is NONE who can remove it except Allaah’. This is because if
all (those from) the creation gathered together in order to bring forth any
type of benefit they would be unable to do so unless Allaah wrote it for them
(thus allowing it). Likewise if (those from) the creation of Allaah gathered in
order to cause harm to anyone, they would be unable to do so unless Allaah
allowed it.
