Like we should adopt Tafweez in worldly matters, so too must we adopt it in spiritual matters. Sometimes, Allah Ta’ala gives a person who is making his Islaah (reformation), an enjoyment or an experience of ecstasy (In Tasawwuf, this state is termed ‘Bast’). The person is on a high. Others take drugs for a ‘high’, but the Allah Waalas, with their Zikr (Praise of Allah Ta'ala), Ibaadat and Ma’rifat, experience a special ‘high’, and there is a world of a difference between these two ‘highs’.
Nevertheless, there are times when these pious ones, who despite doing everything correctly and not disobeying or displeasing Allah Ta’ala, suddenly experience a ‘low’(In Tasawwuf, this state is called ‘Qabdh’). That ‘high’ is no longer enjoyed. They begin to wonder as to what had happened...Why ? And they too suffer depression.
A person, experiencing such a spiritual ‘low’ should reason that there is the great wisdom of Allah Ta’ala behind this state, otherwise it may be that pride enters the person’s heart and he begins to consider himself very great.
This is Allah Ta’ala’s way of keeping a balance. This ‘low’ offsets pride and thus saves a person from spiritual ruin. After this, if Allah Ta’ala so wills, He can always return him to his previous condition.
Thus in worldly as well as spiritual affairs, we need to make an effort and then adopt Tafweez. Ask Allah Ta’ala to make the best decision for us. Plead to Him and beg of Him to give us the best of this world and the best of the hereafter.
