Mawlana Saheb

The question I wanted to ask was if there was a Hadith about saying

السلام علينا وعلى عباد الله الصالحين

when entering a house with nobody inside.

After Salah, I see people going towards the pillars or near the wall and start praying their sunnah. Is there any basis to this in the hadith? Is this an innovation?

What's the status of the narration about Pleiades (Thurayya), knowledge, and Persia?

I wanted to know if a person's ranks actually increase in the hereafter if their children make dua for them. Jazakallahkhaira.

I heard that there is a hadith which mentions if Qiyamah were to occur and you were planting something then you should continue planting it. Where is this hadith located and is it authentic? What is implied by this hadith?

I remember my grandparents encouraging me to eat leftover food stating that the leftover of a Muslim is shifaa (cure) for another Muslim. They emphasized that this is mentioned in the hadith of our beloved Prophet ‘. Therefore, I would like to know the exact words of the hadith and its authenticity. 

Which is the most correct wording of the Hadith: الدعاء هو العبادة or الدعاء مخ العبادة?

There is a hadith that says Allah was a hidden treasure and wanted to be known, so He created the creation. Is this true?

What is the status of the hadith which states that Allah is with the one who has a broken heart?
