Delay in saying In sha Allaah

 

Is it permissible for a person, if he forgot to say “In sha Allaah” to say it after a long time has elapsed?

Praise
be to Allaah.
 

 

Al-Shanqeeti (may Allaah have mercy on him) said: 

Allaah says (interpretation of the meaning): 

“And remember your Lord when you forget”[al-Kahf 18:24] 

There are two well-known scholarly views concerning this
aayah: 

One of which is that
this aayah is connected to that which comes before it, and it means that if
you say, “Tomorrow I will do such and such” but you forget to say “in sha
Allaah”, then after that you remember, you should say “in sha Allah”. In
other words, remember your Lord, connecting everything with His will
concerning what you want to do tomorrow, when you remember after having
forgotten. This is the apparent meaning, because it is what is indicated by
the preceding aayah (interpretation of the meaning): 

“And never say of anything, ‘I shall do such and such
thing tomorrow’” [al-Kahf 18:23] 

This is the view of the majority, and among those who
expressed this view were Ibn ‘Abbaas, al-Hasan al-Basri, Abu’l-‘Aaliyah and
others.
