This document describes a new type of battery that is safer and longer-lasting than current lithium-ion batteries. It works by using sodium ions rather than lithium ions and two different liquids to prevent fires. Sodium is more abundant than lithium, making it potentially more sustainable and less expensive. Tests show the new battery maintains over 90% capacity after 250 charge cycles.
Khadija tested the entity that had appeared to Muhammad to determine if it was an angel or a demon. She had Muhammad describe what he saw when Gabriel appeared while sitting in different locations on her. Each time Muhammad confirmed he saw Gabriel until he could no longer see him when sitting in her lap, leading Khadija to conclude it was an angel since demons cannot disappear. The Quran verse later reminded that a woman's testimony is worth half that of a man.
The document contains 6 hadiths attributed to the Prophet Muhammad discussing medical remedies and treatments. The hadiths discuss drinking camel's milk and urine as treatment, using black cumin seeds for illnesses, the healing properties of certain plants and insects, treating diarrhea with honey, and bloodletting as a beneficial medical practice. The hadiths were recorded in Sahih al-Bukhari and Sunan al-Tirmidhi, two highly authoritative hadith collections.
The document discusses Prophet Muhammad's love and affection for his grandsons Hasan and Hussein.

The document also provides background information on some of the scholars and hadith books mentioned.
