Bid'ah

Q: We live in the same flat eat dinner together, one of the person among us, use to finish dinner late and wash his hands after all of us. Initially I felt like he is following sunnah but later he started doing it intentionally like he finished his dinner before all of us but still waits for all of us and even sometimes if he get up from dining, he don’t wash his hands until and unless we all washes ours. He roams around the house with those unwashed hands. We usually meet for dinner only and this person intentionally starts his dinner in last and washes his hands in last. i.e. after everyone. He is the first guy who sit on dining but still he waits for everyone. Couple of times, I told him to start the dinner, he didn’t, he used some tricks here and there but didn’t started and even same happened to wash the hands after dinner. I am
confused if this is his superstition or sunnah or what? It seems like me others also observed him but never discussed it, as it is quit silly but I feel uneasy joining with such person who has superstition or shirk. Please appreciate if you could spread some light on this activity and send
some rules of eating and ethics.

Q: 

1. Many Madaris and Makaatib have Madrasa holidays on 12th Rabiul Awwal because Prophet Muhammad S.A.W was born on that day. Is it permissible to keep Madrasa holidays on 12th Rabiul Awwal or is it bidah?
2. Did the Sahabah etc keep holidays on  Prophet Muhammad S.A.W birthday?

Q: We have a system in Assam (India) The Ulama of Madaris collects materials and rupees for Madaris and all the Madaris are going on only by these contributions. My question is they give recipits and many people puts these recipits in there tresuare believing that there is baraka in wealth is it right?

Q: The women in our area have this notion that during haidh nifaas they are not allowed to do ghusl with water, moreover they are not allowed to bath during these periods. They say that if they do so they will become ill. Also they do not drink cold water. I understand that bathing and doing ghusl will not not get rid of impurity during these periods but is it true that they are not allowed to use water to clean private parts and/or bath. Please expand on  this topic maybe highlighting the shariah and hikmat perspectives on this issue. Jazakallah

Q: Is it a shar'i ruling to remove clothing from the washing line before maghrib?

Q: During Shab-e-Baraat day after maghrib Namaz people voluntarily without any special prior arrangements having been made do nafl Ibadat in the form of nafl namaaz and recitation of Quran in the form of Surah Yaseen. In such gatherings there happens to be some people who cannot read Quran on their own but they come to the with the desire and expectation to hear the Quran in the form of Surah Yaseen being recited by someone. In order to meet this desire of these people the Imam of the mosque recited the Surah in an audible tone to serve the purpose of these people. Neither the nafl namaaz is performed in Jamaat nor the recitation of Yaseen is recited in unison. So is there any thing wrong in this? Of course the Imam after the Fard Maqrib namaaz does remind the mussalees that it is Shab-e- Baraat night and they should busy themselves with more Ibadat in that night.

Q: I heard many times that do not sweep the floor at night. Is it true according to Islaam?

Q: In local culture, when we address a hafiz of the Quran, we add the name "Hafiz" before mentioning his name, e.g. "Hafiz Zeid". Is this counted as a bida', or is it just a form of respect that we should continue upholding?

Q: What is Bid'at-e-Hasanah?
