Intelligence system is considered to be one of the important tools used by military and civil secret agencies to defend and strengthen a nation. Intelligence system is thought to be one of the oldest studies of known history. Intelligence system consists of correct and accurate information, gathered after great struggle and facing difficulties. This department if related to both peace and war. Intelligence is a basis of formulating all military strategies and plans. The importance of intelligence system both in day to day life and as a nation cannot be overemphasized. This article recounts the intelligence systems and management of the resources of secret services of the companions of the Holy Prophet (SAW) and, thereafter, the Muslims rulers. Furthermore, the principles derived from the era of the companions of the Holy Prophet (SAW) regarding intelligence system have also been discussed in this chapter. The guiding principles that are still valid even today includes: (a) Training of Personnel Since espionage helps to strengthen the roots of a state and protect it from its enemies, therefore it requires a team of well trained professionals with latest technology and trends. Islam emphasized on two aspects of early warning, one is professional and the other is ethical.(b) Counter Espionage. An Islamic state must have an effective network of espionage to keep an eye on all the activities of the enemy. This is known as counter espionage. (c) Reconnaissance. This aims at the fore knowledge of the intentions of the enemy so that one can have a better planning in case of an attack. (d) Verification of Information. Information from an agent should be verified from other sources. An operative may feed false information due to lack of experience and competency and that may create an embarrassing situation. (e) Security of Information. Don’t share your secret, try to protect them. If national secrets are compromised they may cause an extensive damage to national interest. (f) Interrogation of POW. Whenever enemy spies or soldiers are arrested in a war they should be interrogated for extraction of information. They may be subjected to mental stress. (g) Fore Warning of the Enemy. This requires the launching of own agents in the enemy ranks for knowledge of their future plan likes attacks. (h)Treatment of Spies. If anyone is found to be guilty of spying for enemy, he may be penalized with death punishment.

Analysis of Multi-Drug Residues and Their Metabolites in Meat and Milk

Modern farming practices involve administration of a wide range of veterinary drugs and biological substances to food-producing animals with the primary aim to combat diseases and promote growth. The residues of these drugs can enter into food chain either directly or indirectly resulting in serious allergic reactions in humans, and development of drug resistance in multiple strains of bacteria as in case of antibiotics. The main focus of this research work was the development of analytical methodologies for the identification of various classes of antibiotics in broiler chicken and bovine milk using LC-MS/MS. All the developed methods were validated according to European Commission Decision 657/2002/EC and parameters determined are: specificity, accuracy, precision, repeatability, within lab reproducibility, decision limits (CCα) and detection capability (CCβ). The first method developed for the analysis of florfenicol residues in chicken muscles. It was found that most of the florfenicol residues remained bound with tissues and could only be extracted with organic solvents after digestion of the tissues with strong hydrochloric acid at 95-100 °C. The bound residues of florfenicol were present in higher concentration as compared to un-bound residues in various tissues of broiler chicken. The second method was developed for the multi-amphenicol analysis in which florfenicol, florfenicol amine, chloramphenicol and thiamphenicol were simultaneously analyzed. The accuracy values were 86.4 to 108.1% and precision values were 2.7 to 16.3%, respectively. Analysis of the various raw samples confirmed the presence of florfenicol and chloramphenicol residues in few samples at low levels. Third method involved multiclass multidrug residues, in which total 68 compounds from six antibiotic classes were analyzed. The accuracy values were 70- 102.9 % for nearly 87% compounds. The developed method can be used for screening purpose to reduce the number of samples for confirmatory analysis, thus improving the efficiency of the laboratory by reducing cost and time. Lastly, prevalence of penicillin and cephalosporin antibiotics was studied in bovine milk samples obtained from two cities of Punjab, Pakistan using UPLC-MS. Only amoxicillin, ampicillin, Pen G and cloxacillin were found and confirmed in 18 samples.
