For example...
For example, in London (UK) today (15/05/23) Sunset was at 20:47, Maghrib time was 21:06, the stars have not appeared still at 21:38 (so over 50 minutes after the sunset stars have not become visible as there is still light in the sky). Stars start to appear at about 21:52 (~ an hour after sunset). A very similar observation in London was made on next day (sunset 20:47, Maghrib 21:06, end of Maghrib Salat 21:18 and enough still light, at 21:47 no stars until 22:00).
At 1:03 , the reformist contradicts the Usooli Rejal Ahadith criteria by saying even if a Hadith comes from Imam Jafar e Sadiq -asws , which has sound and reliable narrators regarding delaying a few minutes Maghrib Salat after sunset, he would reject it!
And Ahmad bin Muhammad bin Isa narrated on the authority of Saeed bin Janah on the authority of some of our companions on the authority of Al-Reza -asws who said: Aba Al-Khattab was the most corrupt of the people of Kufa, and they did not pray Maghrib until the twilight had passed (stars became visible), and that (allowance) was only for traveller, the fearful, and the needy.
[14] Our reply : The reformist very cunningly avoids the next Hadith (52 under the above 51 Hadith from Tahzeeb ul Ahkaam) of Imam Jafar-e-Sadiq -asws , where Imam -asws says, there is no problem with if one delays his Maghrib Salat until disappearance of redness, see below the Hadith.
