Massallah pertaining to the exchange rate

Assalaam ‘alaikum Mufti Saab, I have come accross the below Q&A from the website – question no. 5691 dated 2010/08/04 – I did not fully understand the answer; therefore as an example to clarify, if the spot exchange rate of the Rand to USD $ today is R 7.00/ 1 USD$ – and I wish to book a forward rate with my bank today, to be settled in 120days time, they quote me R 7.25/ USD$ – if I go ahead with this transaction, will it be permissible?
Wassalaam,
Nashad Dada.
As salaamu alaykum Mufti Saab
Please advise if using exchange rate forward cover in relation to
importing goods from overseas is permissible in Islam.
Jazakallah
