Can we join ‘Isha and Taraaweeh together with Maghrib in Ramadaan if it is raining?

If it is raining at the time of Maghrib in Ramadaan, should we not
join Maghrib and 'Ishaa', or can we join Maghrib and 'Ishaa' and delay
Taraaweeh?
We put this question to Shaykh 'Abd al-'Azeez ibn Baaz (may Allaah
have mercy on him), who replied:
The matter is flexible, in sha Allaah. Putting the prayers together
(in this case) may make the people miss out on a lot of benefits.
And Allaah knows best.
