Purchasing a tupperware package

Q: Is it permissible for a person to purchase a package while not having full knowledge of its contents? Also, there won't be any future disputes since both parties are happy with the sale. For e.g. The company "Tupperware" usually holds a sale once a year where you purchase a 'tupperware package', not knowing the exact quantity or type of tupperwares inside it, but the case is such that whatever you get will definitely satisfy you and turn out cheaper than the normal market value. Hence there is no question of disputes thereafter. Is such a sale permissible?

Doubts regarding purity

Q: I was going through a bad situation where I was having trouble controlling my bladder and with waswasas, this resulted in me urinating myself a bit and also rushing to the toilet resulting in urine getting on my body and on my clothes and on the floor and also sometimes sitting on napaak toilet seats and this resulted in a lot of waswasas, but now I have got medical help things are better but when I was going through the bad situation I either knowingly or unknowingly made things napaak without thinking. I would have touched doors or walls without thinking and also the clothes that I was wearing which were napaak will have touched things whilst I was walking or I may have sat on things or the floor whilst I was napaak or walked whilst my feet were napaak. The thing is I can't really remember what is napaak and what isn't or where did I sit or what did I touch and those things that I do remember I'm not really sure what to do about it and some of it is in public places like the musjid, I always tried my best thinking things over and over again and I have a lot of doubts about what I made napaak so what shall I do?

Sajda-e-tilaawat

Q: Is it mandatory to make sajda-e-tilaawat when reciting the 14 sajda verses of the Qur'an?

Please refer to the Sahih Hadith mentioned below which says it is optional. Narrated Rabi`a RA: `Umar bin Al-Khattab RA recited Surat-an-Nahl on a Friday on the pulpit and when he reached the verse of Sajda he got down from the pulpit and prostrated and the people also prostrated. The next Friday `Umar bin Al-Khattab recited the same Sura and when he reached the verse of Sajda he said, "O people! When we recite the verses of Sajda (during the sermon) whoever prostrates does the right thing, yet it is no sin for the one who does not prostrate." And `Umar did not prostrate (that day). Added Ibn `Umar "Allah has not made the prostration of recitation compulsory but if we wish we can do it." (Bukhari - Vol. 2, Book 19, Hadith 183)
