قیام امن میں اصحاب صفہ کا کردار

Almighty Allāh sent his messengers to lead and guide the human beings. One of the lessons we learn from the lives of the prophets and their struggles is the significance of the presence of a peaceful environment. During the lifetime of our holy Prophet establishment the for examples numerous find we, (صلى الله عليه وسلم) Muhammad and maintainance of peace. The Arab society was famous for battles and the people were wild in nature, but, with the arrival of Islām, they became the most loving and peaceful society in the world. This article focuses on the role of Aṣḥāb al-Ṣuffah in maintaining and promoting peace. Aṣḥāb al-Ṣuffah was a group of people who stayed at the northern corner of al-Masjid al-Nabawī under the constant watch of the Prophet (ﷺ) himself. Aṣḥāb al-Ṣuffah lived in a and life his observed They. (صلى الله عليه وسلم) Prophet the to proximity closed learnt from his lectures. So, it can truly be called the first school of the Islamic history. A number of students, schooled in al-Ṣuffah were sent to the different parts of the Arabia and later, to other parts of the Islamic empire, to disseminate the message of peace and love among the people. Their efforts are a significant part of the Islamic history in the promotion of peace.

Diagnostic Accuracy of a Commercial Cross Priming Amplification Diagnostic Kit in Smear Negative Sputum

Background: The diagnosis of smear negative tuberculosis remains a major obstacle to global control of tuberculosis (TB), especially in resource limited settings. Several nucleic acid based diagnostic tests have been developed to improve diagnosis. The polymerase chain reaction has been the benchmark for nucleic acid amplification; many novel alternatives have been developed for the amplification and detection of nucleic acid sequences. Objective: The study aimed to determine the diagnostic accuracy of Cross Priming Amplification technology using the Ustar TB Isothermal Amplification Diagnostic (IAD) Kit (Ustar Biotech, Hangzhou, China) in smear negative sputum. Methods: 159 unconcentrated sputum samples negative by direct Ziehl-Neelsen staining referred to the National Central Reference Lab in Nairobi were subjected to both the Ustar TB Isothermal Amplification Diagnostic Kit and culture. The reference standard was TB culture. Results: When tested on Ziehl-Neelsen negative smear sputum, the IAD assay was found to have a sensitivity of 75% (60-86%; 95% CI); Positive Predictive Value (PPV) of 84% (71-94%; 95% CI) and Diagnostic Odds Ratio of 42.18 (15.65-113.69; 95% CI). The specificity of the assay was 94% (87-97%; 95% CI). Conclusion: The assay demonstrated good sensitivity and moderate specificity in detecting mycobacterium tuberculosis in smear negative specimen, the requirements for a clean room for the DNA extraction procedure, a high speed centrifuge and biological safety chamber may limit the applicability of this technique in resource limited settings.
