Frequently reciting "Bismillah"

Q: As in a Hadith it is recommended to "start" any task with "Bismillah". So I want to ask if one says "Bismillah" frequently not only in the start of any task but in the middle or end as well. Or if one makes it his/her frequent zikr even without any task. Is it allowed and benefiting for a Muslim or it is an an addition to the sunnah?

Participating in a protest for Palestine

Q: Are you aware on 9th August 2025 there will be protest in London only if 500 people sign up for it. This protest is there to deprescribe Palestine action as terrorist group. As Muslims, will it be considered jihad if we participate in this protest? There is chance of you getting arrested if you join. Do you think we as Muslims should join this protest? 

Also, they said we can only have signs that has below message nothing else as you can easily be targeted by police if you have different messages compared to masses. Only message they allow is "I oppose genocide" "We support Palestine action" 

Palestine action is a group that damaged elbit system sites in UK. Elbit systems supply weapons to Israel. UK government has banned Palestine action and there will be many protests like these to try and get Palestine action unbanned. Is it jihad if Muslims participate in these protests?

Imaam going into ruku after reciting a sajdah aayat

Q: A few days ago, our imam recited Surah Alaq in the second rakah of Isha salaah. When he recited the aayah of sajdah, he did not perform the sajda-e-tilawat but went into ruku' and completed the salaah as normal. 

My question is: was he right in omitting to do sajda-e-tilawat which my understanding is to be wajib. After the salaah he explained that what he did was permissible.

Saying "madad 'Abdulqadir"

Q: If someone asks is it permissible to say madad 'Abdulqadir or Badawi or Naqshibandi (or the like), what is the answer to this? Meaning, does Sayyid 'Abdulqadir (or the like) hear when someone says that from a far with the permission of Allah? Is there any other meaning of madad? 

PS - I'm learning aqeedah and I need an explanation of this. Linguists say that ibadah is not defined as merely calling or asking for help from someone. Subki rahimehullah says ibadah is ultimate submission and subjugation. How can I understand the given topic.

Responsibility of fixing a car that broke down while test driving it

Q: Please advise me on how to go about this problem: 

I smashed my brothers car so I decided to replace him with a very similar car. I saw the car in some pictures which was being sold by a reputable trustable person. After speaking to the seller on the phone I was happy with what he told me about the car. But the seller told me its better I first have a look at the car, drive the car then we will speak about method of payment. We agreed on a meeting point. 

The seller drove for about 150km. My brother went to pick up the car and drove it for another 200km and as he entered the town before reaching home, the car broke down. 

Am I responsible for the breakdown? Please advise on whats the way forward.
