During the Covid-19 pandemic, the use of online sports programs became popular. The purpose of this study was to investigate the effect of eight weeks of online body balance program on anxiety, depression, and aggression of children with attention deficit/hyperactivity disorder (ADHD). Body balance is a sport based on yoga, tai chi, and Pilates. The present study was a semi-experimental and applied type of study. The participants of the present study were 30 volunteer children with ADHD who were divided into two experimental (15 people) and control (15 people) groups by random assignment method. Aggression, depression, and anxiety variables were evaluated by Bass and Perry questionnaire, Maria Kvas children's depression questionnaire, and Revised Children's Manifest Anxiety Scale. The experimental group performed online body balance training for 8 weeks (3 sessions per week for 60 minutes) online, and the control group did their current activities. In order to investigate intra-group and inter-group differences, repeated measures ANOVA at the error level of 0.05 was used by SPSS software. The results showed there was significant difference in the average level of symptoms of depression, anxiety and aggression in the pre-test and post-test stages (P≤0.05), between the two control and experimental groups (P≤0.05) and the interaction effect of time and group (P≤0.05). The results of Tukey's test showed that there was a significant reduction of these symptoms between the two experimental and control groups in the variables of depression symptoms (-5.500), anxiety symptoms (-5.133) and aggression symptoms (-13.133). Based on the results of this research, eight weeks of body balance training reduced depression, aggression and anxiety symptoms in 7-9 year old children with attention deficit/hyperactivity disorder. Therefore, the improvement of mental disorders caused by this disease in children following the body balance exercise program emphasizes the importance of using this intervention method for children with ADHD.

The Holy Qur’an, in addition to its primary purpose of guiding humanity, contains numerous scientific references that were not fully understood at the time of its revelation. Verse 25 of Surah al-Ḥadīd refers to the sending down of iron. The use of the verb anzala (to send down) instead of more commonly used verbs such as khalaqa (to create) and jaʿala (to make) has led to various interpretations of this verse throughout history. This research employs a descriptive-analytical method to examine the concept of the sending down of iron (inzāl al-ḥadīd) and its strong nature (ba's shadīd), as well as its relation to new scientific findings regarding the origin of iron on Earth. Additionally, it investigates whether people at the time of the Qur’an’s revelation had any knowledge of the extraterrestrial origin of iron.Contrary to some extreme approaches to the scientific interpretation and miracles of the Qur’an in recent centuries, this research advocates a balanced perspective that utilizes scientific findings, without any imposition, to better understand the verses of the Qur’an. Recent scientific discoveries indicate that iron is primarily produced in the cores of massive stars, and it cannot be produced in the solar system. Therefore, the use of the verb anzala may allude to the extraterrestrial origin of iron. The results of this research reveal that, from a scientific standpoint, various phenomena are involved in the process of iron's incorporation into Earth that could embody the concept of "sending down," including the production of iron in massive stars and its transfer to Earth through certain cosmic processes, the collision of iron-rich meteorites and asteroids with Earth, and the sinking of iron towards the Earth's core. Regarding the knowledge of people about the extraterrestrial origin of iron at the time of revelation, although it has been claimed that the term used for iron in ancient Egypt means "metal from heaven," the findings of this research indicate that this claim is merely a possibility and, despite extensive research, has not been definitively verified.
