IN VITRO ASSESSMENT OF ANTIMICROBIAL AND ANTIOXIDANT ACTIVITIES OF EXTRACTS OF YEMENI FAGONIA SCHWEINFURTHII HADIDI
No full textBackground: Antioxidant and antimicrobial properties of plant extracts are attributed to bioactive components derived from medicinal plants. This study inspected into the antimicrobial and antioxidant effects of extracts from Fagonia schweinfurthii Hadidi aerial portions.
Method: Several solvents, including n-hexane, ethyl acetate, and methanol, were utilized sequentially to extract secondary metabolites from F. schweinfurthii aerial parts. Antimicrobial activity was evaluated using the well diffusion method and broth serial dilution, whilst antioxidant activity was evaluated using the 2, 2-diphenyl-1-picrylhydrazyl radical scavenging method.
Results: The findings exposed that the studied fungal strains (Candida albicans and Trichophyton rubrum) were resistant to all plant extracts. F. schweinfurthii methanol and ethyl acetate extracts demonstrated inhibitory effects on Gram-positive and Gram-negative tested bacteria with minimum inhibitory concentration between 2.5 and 20 mg/ml. In addition, the most sensitive bacterium was Proteus vulgaris, with an inhibitory concentration (2.5 and 5 mm). While the most resistant bacterium was Staphylococcus epidermidis. Due to the physical and chemical properties of the solvents, different extracts of F. schweinfurthii aerial parts exhibited diverse antioxidant capabilities in the antioxidant activity experiment. Methanol and ethyl acetate extracts exhibited IC50 values of 236 ± 0.2µg/ml and 359.4± 0.6µg/ml, respectively.
Conclusion: According to the findings of this study, the aerial portions of F. schweinfurthii could be considered a possible source of natural antioxidants as well as a valuable source of antibacterial agents against bacteria that cause ear infections.

Pendidikan Sosial dalam Al-Qur’an
No full textThe values of social education today no longer reflect the
beauty of the values that have been taught by the Qur'an, this
can be seen from the many actions that violate social values, the
most obvious example is mocking or making fun of others and
there are many other examples. and sadly, things like this are
considered to be a normal thing and even become a current
trend on social media. Seeing the urgency of the problems
related to social education, the author feels that research on
social education will discuss in such a way about this topic by
focusing on social education which is certainly based on the
Qur'an. This means that the problem that the author will discuss
includes social education in the Qur'an by including several
verses of the Qur'an related to this discussion as well as the
interpretation of the verse in the hope of improving our social
life system based on what has been stated in the Qur'an. Qur'an,
but because of the limitations of the author in reviewing the
verses of the Qur'an related to social education, the verse that
the author will discuss is QS. Al-Hujarat verses 11-13 and QS.
Ali Imran verse 112. By using a library research methodology,
the authors get the results of the research that the value of social
education contained in the Qur'an, especially the two suras, is
that in social life a person is recommended to have an attitude
of tolerance, not to make fun of and ridicule others, do not be
prejudiced and do not look for the faults of others and maintain
relationships with God and fellow human beings, thus these
values will be applied in the implementation of social
education

No full textFazl b. Sehl, Mecûsî bir ailenin çocuğu olarak 154/771 yılında Serahs'ta dünyaya geldi. Babasının bir vesile ile Bermekîler'le tanışması üzerine Yahyâ b. Hâlid b. Bermek'in Hârûn er-Reşîd'e tavsiyesi sayesinde Me'mûn'un maiyetine girdi ve onun davetiyle 190/ 805?806 senesinde Müslümanlığı kabul etti. Hârûn er-Reşîd'in ölümü sonrasında oğulları Emîn ve Me'mûn arasında çıkan iktidar mücadelesinde, askerî ve siyasî yönetimiyle Me'mûn'un halife olmasını sağladı. Kazandığı başarılardan dolayı Me'mûn tarafından sınırsız yetkilerle donatıldı ve kendisine Zü'r-Riyâseteyn lakabı verildi. Devlet yönetiminde İranlı unsurlara ağırlık verdi ve devletin şeklini Sâsânî imparatorluğunun yapısına benzetmeye çalıştı. Me'mûn'un Şia'nın oniki imamından Ali b. Mûsâ er-Rızâ'yı veliaht tayin etmesinde etkili oldu. Bu yüzden Şiî taraftarı olmakla itham edildi. Kendisine muhalefet eden Abbasî devlet adamlarından Herseme b. A'yen'in Me'mûn tarafından öldürülmesine sebep oldu. Bunlarla birlikte çıkan isyanların bastırılmasında gösterdiği başarısızlık yüzünden ve Bağdat'ta Abbâsoğulları'nın Me'mûn'u azletmesi üzerine olayların sorumlusu olarak kabul edildi. Me'mûn'un işleri eline almak üzere çıktığı Bağdat seferi esnasında, 2 Şaban 202/13 Şubat 818'de Serahs'ta suikast düzenlenerek öldürüldü. Fazl b. Sehl her yönüyle Bermekîler'e benzemekteydi.
